This study explored creative problem solving in lucid dreams, where the dreamer is aware they are dreaming. 9 experienced lucid dreamers and 9 non-lucid dreamers were given logical puzzles or tasks to create metaphors over 10 nights. Lucid dreamers were asked to find a knowledgeable dream character for help. Preliminary findings suggest lucid dreams may aid creative but not logical tasks. Dream characters provided plausible creative advice. The study revealed methodological considerations for future research.
The document summarizes a study that will examine the effects of lucid dreaming on depression. Twenty-four subjects diagnosed with major depressive disorder will be divided into four groups. Groups A and B will receive lucid dreaming training, while groups C and D will serve as controls. The study aims to see if lucid dreaming can help treat depression by allowing patients to alter nightmares. Subjects will track dreams using logs and undergo evaluations after three months. The researcher hypothesizes that lucid dreaming will improve sleep and mood in depressed patients.
The study aims to examine whether lucid dreaming can help treat depression. Subjects with depression will be divided into four groups. Two groups will receive lucid dreaming training while the other two will not. One group receiving training will also take antidepressants. Subjects will keep dream logs and be evaluated after three months to see if lucid dreaming improved their mood, behavior, and depression symptoms. The researchers hypothesize that by gaining control over dreams through lucidity, subjects can alter nightmares and improve sleep, which may help treat their depression.
This document summarizes experimental research on dreaming. It discusses how dreaming has been studied experimentally since the 19th century by examining dream content and frequency. A key finding is that rapid eye movement sleep was proposed as the physiological basis of dreaming, but this was later challenged as it did not fully explain dream characteristics. The research concluded that understanding dreaming requires a focus on individual experiences and unconscious processes. Participants in one study included men and women of varying ages, and findings showed gender differences in dream content. Overall, the research suggests a psychoanalytic perspective could provide new insights into dreaming by addressing concepts like personal meaning and unconscious memory.
The Effects of Sleep Deprivation on Item and AssociativeReco.docxtodd701
Sleep deprivation reduces the quality of information (drift rate) accumulated in memory-based decision making, according to a study using a diffusion model. The study compared the effects of total sleep deprivation on two memory tasks: item recognition of individual words and associative recognition of word pairs. Results showed sleep deprivation reduced drift rate, indicating degraded memory, with little effect on other decision processes. This suggests sleep deprivation may degrade attentional processes needed for forming associations in memory.

This document summarizes a proposed study that aims to investigate the effects of subliminal/supraliminal presentation and shallow/deep levels of processing on explicit memory performance in older adults. The study uses a 2x2 within-subjects design to manipulate presentation type (subliminal vs supraliminal) and level of processing (shallow vs deep). It is hypothesized that deep processing combined with subliminal presentation will yield the highest memory performance scores. Around 50 older adult participants will complete a memory task involving word lists under the different conditions. Their memory will be assessed using a recognition test.

This document provides instructions for writing a book report on the non-fiction novel "Zeitoun" by Dave Eggers. It discusses the plot of the book, which follows a Syrian-American man named Zeitoun who stays in New Orleans during Hurricane Katrina to protect his properties, and is later imprisoned for unknown reasons. The summary notes that the book portrays Zeitoun as an unbreakable hero, but the teacher has revealed that the author provided subtle clues suggesting a more complex characterization of Zeitoun and his relationship with his wife.
This document discusses sleep disruption and cognitive impairment. It presents a modified modal model of memory that includes perception, attention, and short-term and long-term memory stores. Sleep fragmentation and reduced slow-wave sleep and REM sleep are linked to impairments in these cognitive functions. Studies show reduced brain activity in older adults' prefrontal cortex is associated with changes in slow-wave sleep and poor long-term memory. Sleep disruption from sleep apnea is also linked to deficits in attention, memory, and executive function. New technologies may help better measure sleep to improve treatment and reduce cognitive decline with age.
The document summarizes a longitudinal case study report for a PhD thesis on dream formation, function, and interpretation in workplace conflict situations from 2004-2011. It includes chapters on introduction, literature review, methodology, results, discussion, summary, and conclusion. The introduction defines dreams and discusses dream theory and interpretation approaches. It notes dreams are personal and reflect one's concerns. The case study investigated how dreams related to psychological well-being and differences in dream content between normal and clinical groups.

The study explored the relationship between hallucinations and inhibitory deficits in memory processes among schizophrenic patients. Two experiments were conducted using directed forgetting and working memory tasks. The results showed that patients with hallucinations had difficulty intentionally inhibiting irrelevant memories in both episodic and working memory, as evidenced by a lack of directed forgetting effect and higher number of intrusions. This suggests hallucinations may arise from a failure to inhibit intrusive thoughts and memories.
The Cornell Memory and Neuroscience Lab studied the relationship between memory processes and brain volume in older adults using data from the Alzheimer's Disease Neuroimaging Initiative. They found that memory parameters estimating verbatim and gist memory, as well as forgetting, were independent of both raw and relative brain volume measures across current diagnostic groups and transitions between diagnostic categories over time. This suggests that while both memory changes and brain atrophy are predictors of Alzheimer's disease, they do not predict each other. Functional network connectivity may have a stronger association with memory performance than brain volume.
This document contains an ethical statement, acknowledgements, abstract, introduction, materials and methods, and references sections from a research paper. The introduction discusses implicit and explicit memory systems and how they are affected differently by stimulus exposure duration based on prior research. The study aims to investigate how varying exposure durations from 40ms to 1900ms impacts performance on implicit (priming) and explicit (recognition) memory tasks. It is hypothesized that priming performance will increase up to 250ms exposure and then decrease, while recognition performance will increase with longer exposures. The materials and methods section describes that 20 participants were split into implicit and explicit memory conditions and completed a priming or recognition task with pictures exposed for different durations.
Dreams have been linked to several important scientific discoveries and creative works. The document discusses how REM sleep, the sleep stage associated with vivid dreaming, can boost creativity by allowing the brain to make unusual connections. Researchers found that volunteers who took a nap and reached the REM stage performed 40% better on a creative word game afterwards. While the dreams themselves may not directly relate to improved creativity, the loose cognitive associations during REM sleep appear to aid innovative thinking. Harnessing the creative power of dreams may be possible for many people with a little REM sleep.
This document summarizes Freud's view of dreams and the evolution of his theoretical approach. It discusses:
1) Freud initially viewed dreams as reflections of biological-psychological mechanisms that are universal. He analyzed individual dreams to develop broader theories, similar to studying specimen morphology.
2) Freud later abandoned direct anatomical descriptions and illustrations, instead using conceptual diagrams unrelated to physical structures. He developed metaphorical models of mental structures like the ego and id.
3) Freud's theoretical shift recognized that dreams reflect cognitive limitations during sleep rather than serving as occult messages. It moved his work from proposed neurological explanations to interpretive hermeneutics using metaphorical reasoning.
This paper discusses the search for the neural correlate of consciousness (NCC) and the challenges involved given that consciousness cannot be directly measured. It notes that while neuroscience research has proposed many potential NCCs, the conceptual foundations for interpreting this research are still being established. The paper argues that identifying an NCC relies on implicit "bridging principles" to infer consciousness from neural data, such as assuming reports indicate consciousness. However, these principles are philosophically grounded assumptions rather than empirically tested. The paper aims to make these interpretive foundations more explicit to better understand the reasoning behind NCC research.

The document discusses theories about the functions of sleep. It suggests sleep may serve functions like immune function, muscle/organ function, toxin removal, energy replenishment, neural regeneration, learning and memory, and more. However, determining sleep's exact functions is challenging. The document outlines challenges like distinguishing functions from interactions and disentangling sleep from biological clocks. It discusses clues from development, molecular biology, and evolution to help understand sleep functions.

False. Cultural relativism and moral relativism are not exactly the same. Cultural relativism is the view that cultural practices and beliefs should be understood based on the cultural context from which they arise rather than being judged against the standards of another culture. Moral relativism is the view that moral truths are relative to the culture or society holding them rather than being absolute. So cultural relativism focuses on understanding other cultures, while moral relativism focuses on whether moral claims can be objectively true or false.

The document discusses theories about the functions of sleep. It suggests sleep may serve functions like immune function, muscle/organ function, toxin removal, energy replenishment, neural regeneration, learning and memory, and more. However, determining sleep's exact functions is challenging. The document outlines challenges like distinguishing functions from interactions and disentangling sleep from biological clocks. It discusses clues from development, molecular biology, and evolution to help understand sleep functions.

False. Cultural relativism and moral relativism are not exactly the same. Cultural relativism is the view that cultural practices and beliefs should be understood based on the cultural context from which they arise rather than being judged against the standards of another culture. Moral relativism is the view that moral truths are relative to the culture or society holding them rather than being absolute. So cultural relativism focuses on understanding other cultures, while moral relativism focuses on whether moral claims can be objectively true or false.

The document discusses two short stories by Nikolai Gogol, "The Nose" and "The Overcoat", that end with a balance of power rather than a happy ending. In "The Nose", a man's nose rises to a higher social rank than him before returning to his face. In "The Overcoat", a man's coat, a symbol of power, is stolen after he saves to buy a new one, leaving him powerless, though he later steals a coat from a man he feels is responsible. Both stories show the rise and fall of power before ending in a similar balance of power as the beginning.

The characters of Romeo and Mercutio in Shakespeare's Romeo and Juliet serve as foils to each other. While Romeo is a romantic lover who expresses his love through words, Mercutio is cynical about love and sees it as insignificant. He encourages Romeo to have casual sex instead of pursuing a serious relationship. Mercutio also seems jealous of Romeo's love for Juliet. The two characters present contrasting views of love and relationships that underscore major themes in the play.

The document discusses the enforcement of rules in American football by organizations like the NFL and NCAA. It notes that rules have gradually changed over the years to make the game safer and less violent. However, some argue this has made football too soft compared to the past. New rules like targeting bans certain tackles and leads to more penalties being called, which slows down defenses and reduces exciting big hits. While safety was the goal, some feel the rule changes have negatively impacted the game.

Great Writing 2 Great Paragraphs (EditionKarla Adamson
The passage discusses how the horror genre shifted in the late 1980s/early 1990s to portray serial killers as humans living among society rather than masked figures. This changed the "Final Girl" character, exemplified by Clarice Starling in Silence of the Lambs, who must face internal rather than external threats. By confronting more psychologically complex villains, these films explored how violence relates to sexuality in a way that still resonates with audiences today.

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...indexPub
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

Creative problem solving in lucid dreams
1. Introduction
Throughout history dreams have been a wellspring of inspi-
ration for many. Scientists, inventors, writers, artists found
insights and clues to long-awaited answers while dreaming.
F.A. Kekulé’s discovery of the structure of the benzene mol-
ecule; O. Loewi’s idea for the Nobel Prize winning experi-
ment with a frog’s heart; E. Howe’s invention of the sewing
machine; R. L. Stevenson’s famous novella “The Strange
Case of Dr. Jekyll and Mr. Hyde” are just a few famous an-
ecdotal examples of dream-inspired problem solving and
creativity (cf. Garield, 1976). Creative dreaming is not a
privilege of a few gifted individuals, it plays an important
role in the lives of ordinary people – it has been estimated
that about 8% of our dreams provide creative insights to our
waking life problems (Schredl & Erlacher, 2007).
Although various dream incubation practices, aiming to
receive answers to questions or obtain cures from sickness,
existed in many ancient cultures (cf. Garield, 1976), there
is still relatively little known from the scientiic point of view.
Laboratory studies suggest that sleep loss and deprivation
of dreaming, or of REM sleep, impairs creative thought and
adaptation to stress (Glaubman et al, 1978; Greenberg, Pil-
lard & Pearlman, 1972; Horne, 1988), however only very few
studies have enquired whether dreams can contribute to
creative problem solving.
Cartwright (1974) in a laboratory study asked student
participants to accomplish three different types of tasks -
crossword puzzles, the Remote Associates Tests (RAT), and
Thematic Apperception Test (TAT) story completions. These
were done after a period of sleep, which included the REM
stage, and after an equivalent period of wakefulness. The
only difference between the two conditions was that sleep
and dreaming resulted in less positive TAT story endings.
However the quality of stories was not assessed in this
study. Schatzman (1983a, 1983b, 1986) published several
brain-teasers in the New Scientist magazine and received a
number of dream reports solving these problems. However
there is no way to establish the total number of people who
actually tried to solve these problems with dream incubation
techniques.
Barrett (1993) asked 76 college students to select a prob-
lem of personal relevance which had a possible solution and
to follow a dream incubation procedure each night for one
week or until they had a dream with a solution to the prob-
lem. About a half of the participants had a dream related to
the problem and a majority of these (70%) were considered
by the participants as containing a solution. Independent
judges rated half of the problem-related dreams to contain
a possible solution.
White and Taytroe (2003) randomly allocated 96 par-
ticipants into a control and four experimental conditions.
Participants were asked to choose between one and eight
personal problems and to rate their solvability and level of
distress at the beginning and at the end of ten days study,
while keeping daily records of their dreams and moods.
Experimental participants were asked to review cognitively
one particular focal problem each day and to use either a
dream incubation technique before going to sleep or after
waking in the morning, or to use a relaxation technique be-
fore sleep or after awakening. The participants that used
night dream incubation technique were more likely to report
greater problem solvability, lower level of distress and great-
er improvement in their focal problem in comparison with
the controls. Their daytime anxious and depressed moods
also decreased over the period of study.

Summary. Both historical accounts and modern research suggest that dreams may contribute to creativity and prob-
lem solving, however no research has been done to investigate creative problem solving in lucid dreams – in which the
dreamer is aware that he or she is dreaming. This pilot and exploratory study explored the feasibility of such research. It
was also hypothesised that dream characters might help the dreamer. Nine lucid dreamers (the experimental group) and
nine non-lucid dreamers (the control group), for ten consecutive nights, had either to solve a logical puzzle or to create a
metaphor. The preliminary indings suggest that lucid dreams can contribute to problem solving when dealing with more
creative rather than logical tasks and that dream characters can provide plausible creative advice to the dreamer. Several
methodological considerations were revealed that should be addressed in future studies.

I J o R Creative problem solving in lucid dreams
A recent study by Cai et al (2009) investigated the role of
REM sleep on creative problem solving, using the Remote
Associates Test while manipulating various conditions. In
comparison with quiet rest and non-REM sleep, REM sleep
was found to enhance the integration of unassociated infor-
mation for creative problem solving during a nap. REM sleep
increased the performance by almost 40%, while there were
no improvements in NREM sleep and quiet rest conditions.
The authors also established that prior exposure is neces-
sary for creative problem solving and that REM improve-
ments in creative problem solving are not simply the result
of improvements in memory. The advantage of REM over
NREM sleep in problem solving was also demonstrated by
Walker et al (2002). Their participants were awakened after
10 minutes into NREM and REM sleep and were given ana-
gram word puzzles to solve. It was found that awakenings
immediately following REM sleep provided a signiicantly
greater number of anagrams solved in comparison with
NREM awakenings.
However none of this research has investigated creative
problem solving in lucid dreams – in which the dreamer is
aware that he or she is dreaming and can consciously in-
luence the dream content (LaBerge, 1985). Although lucid
dreaming is not widely known or understood, and is con-
sidered to be a rare phenomenon, it is estimated that about
58% of the population have experienced a lucid dream at
least once in their lifetime and about 21% are having lucid
dreams regularly - at least one lucid dream per month (Sny-
der & Gackenbach, 1988). It is a learnable skill (LaBerge,
1980) and there are a number of techniques suggested for
lucid dreaming induction (e.g. Gackenbach, 1985; LaBerge
& Levitan, 1995; LaBerge & Rheingold, 1990; Tholey, 1983).
LaBerge and Rheingold (1990) provide an anecdotal ac-
count of a computer programmer who used lucid dreams
regularly for a computer program design. In his dreams, the
programmer discusses the program with a dream character
that represents Albert Einstein; they draw some lowcharts
on a blackboard until they come up with a solution, which
is usually 99% accurate (ibid. pp. 216-217). Tholey (1989)
found out that at least some dream characters in lucid
dreams are capable of remarkable cognitive achievements –
they were able to write and draw, to rhyme, and even to say
an unknown word to the dreamer, although they somehow
struggled with arithmetic. Experienced lucid dreamers also
observe that some dream characters appear as knowledge-
able personas that describe themselves as guides and of-
fer assistance or support to the dreamer (Waggoner, 2009).
Considering that the content of lucid dreams mostly seems
to depend on the dreamer’s expectations (LaBerge, 1985;
Waggoner, 2009), it seems plausible that knowledgeable-
looking igures, such as Albert Einstein or an old wise guru,
might provide credible advice to the dreamer.
In this pilot and exploratory study we explored the fea-
sibility of creative problem solving in lucid dreams and en-
quired whether it might be beneicial for a dreamer to ask
a knowledgeable-looking ‘guide’ or ‘guru’ dream igure for
help with problem solving.
2. Method
2.1. Participants
Nine experienced lucid dreamers were recruited to the
study by placing adverts on discussion boards in three lu-
cid dreaming related websites (ld4all.com, mortalmist.com
and dreamviews.com). The age range was 18-41 years
(M = 26.2, SD = 8.0). There were four males and ive females
and all were English speakers (4 native and 5 non-native).
The lucid dreamers comprised the experimental group. The
control group consisted of nine non-lucid dreamers with a
good dream recall. A mixed strategy and purposive sam-
pling procedure was used to match the control group with
the demographic characteristics of the experimental group.
One participant in the control group was recruited through
a lucid dreaming related website, while the others were re-
cruited by sending group emails to a number of people, di-
rectly or indirectly known to the researchers, inviting ones
with good dream recall to take part in a study about dreams
and creative problem solving. Three participants, who were
known to have an interest in dreams, were invited to par-
ticipate because they matched the characteristics of the
experimental group. The age range of the control group was
19-41 years (M =26.9, SD = 6.7). There were three males
and six females and all were English speakers (4 native and
5 non-native).
Participants were recruited from different countries and
continents, including Europe, Northern America and Aus-
tralia. Although some of the participants were not native
English speakers, all of them had a good command of the
English language. All correspondence between the partici-
pants and the researcher was by emails in English. Partici-
pation was voluntary and unpaid. The ethical approval for
this study was received from Liverpool John Moores Univer-
sity’s Research Ethics Committee.
2.2. Procedure
The study was designed as a ield experiment. For a period
of ten consecutive days, each evening at 9 pm (21:00) their
local time, the participants received an email with a task for
that particular night to solve. The participants were asked to
write down the task on a piece of paper or print it out and,
before going to sleep, to read the task several times and try
to memorize it without solving it.
The lucid dreamers were further advised to attempt to in-
duce a lucid dream using their preferred technique. Once in
a lucid dream, they were encouraged to believe that there is
someone in their dream who knows answers to many ques-
tions and is willing to help the participant. It was suggested
that it may be an old wise man or woman, a ‘guru’ igure or
a ‘guide’. The participants were asked to ind this dream
igure or to call him or her to appear. A speciic sequence of
movements was also suggested which participants could
use if they were not able to ind such a dream character (to
go forward, turn to the left, ind a door, open it, go through
the door and turn to the right). It was expected that this
might increase the expectations of the participants and thus
the chances of inding the required dream igure. Once the
lucid dreamers had found the guide igure, they were en-
couraged to ask him or her to solve the problem given to
them. Even if the answer provided seemed not to be valid,
the participants were asked to thank the ‘guide’ igure, to
wake up themselves and to write down the answer and a
description of the dream.
If the lucid dreamers were not successful with the comple-
tion of the whole procedure (inducing a lucid dream, inding
a dream ‘guru’ character, obtaining the answer) they were
asked to follow the same procedure as the control group:
upon awakening in the morning to relect on their dreams

Creative problem solving in lucid dreams
and to write the irst solution which then came to their mind,
providing also a description of the most vivid dream of the
night. They were also asked to send their report to the re-
searcher on the same day. Participants also indicated in the
report whether the answer was provided in the dream or by
themselves. The lucid dreamers also speciied whether they
were able to induce a lucid dream, to ind a guide igure, and
to obtain an answer from the guide. This was also later veri-
ied by the researcher by comparing the dream descriptions
provided by the participants.
Participants were not allowed to discuss their tasks with
anyone else until after they had sent the report to the re-
searcher. During the whole period of study, they were also
prohibited from discussing the tasks, or their dreams and
experiences of the study publicly or with people who might
also participate in the project (e.g., on dream-related inter-
net forums). At the end of the study, the participants were
asked to relect and share with the researchers their per-
sonal experiences, thoughts, and insights during the period
of research.
2.3. Tasks
Two different types of tasks were used in the study: the
participants had either to solve a logical puzzle or to cre-
ate a metaphor for a speciied situation. Logical tasks were
selected from various sources, while metaphor tasks were
chosen to relect an unusual and ambiguous situation in or-
der to avoid possible automatic associations. The order of
task presentation was randomized. The tasks are shown in
Table 1.
Logical tasks were assessed for their correctness (either
correct or not), while the metaphors were evaluated by two
judges (University tutors in psychology) who ranked them
accordingly to four criteria: originality, aptness, validity and
aesthetic it or “elegance” (cf. Barron, 1969). One judge
(Judge 2) was the second author. Both judges were blind to
which group participants belonged to, although both judg-
es understood the purpose and protocol of the study. The
judges initially were asked to provide an overall evaluation
of the metaphors (considering the four criteria together) and
to rank the different answers for each task, assigning the
rank 1 to the best answer, 2 to the second best, and so on.
Subsequently they were also asked to evaluate the meta-
phors by each criterion separately, i.e. to rank the answers
for originality, aptness, validity and elegance. To avoid pos-
sible ambiguity, the distinction between aptness and valid-
ity was also clariied for the judges, who were advised to
consider aptness as a more subjective measure (how well “it
clicks”, or gives the right impression), while validity should
be considered as more objective measure (how directly the
images corresponded).
If the participant had not provided the answer to a logical
task, it was considered as an incorrect answer (fail). A failure
to provide an answer to a metaphor task resulted in an au-
tomatic assignment of the average lowest rank (e.g. if seven
out of 10 participants provided their answers, they were as-
signed ranks in the range of 1-7, while the other three par-
ticipants who did not provide their answers were assigned
the same average lowest rank of 9 = (8 + 9 + 10) / 3).
2.4. Statistical testing
Chi-Square analysis (two-tailed) was used to compare
the answers to the logical tasks between the two groups.
Answers to the logical tasks for all other conditions were
compared by employing Fisher’s exact probability test (two-
tailed), because sample sizes used were small.
Spearman’s rho coeficient (one-tailed) was calculated to
assess the agreement between the two judges’ rankings
of the answers to the metaphor tasks. The answers to the
metaphor tasks among different conditions were compared
by using the Mann-Whitney U test (two-tailed) for the rank-
ings assigned by the two judges.
SPSS 14 software was used for statistical analysis.
Table 1. Tasks given to the participants
Day Task
Day 1 What is the missing letter in the sequence? W, I, T, M, ?, I, T, S
(Answer: L - initial letters of the presented sentence)
Day 2 To create a metaphor for: “Lighthouse in a desert”
Day 3 What is curious about the sentence: “Show this bold Prussian that praises slaughter, slaughter brings rout”?
(Answer: without irst letters of each word the sentence still makes sense)
Day 4 To create a metaphor for: “Banknote loating in a river”
Day 5 To create a metaphor for: “Child playing in a cemetery”
Day 6 There is an open bottle of beer in the centre of a small rug. The problem is to get the bottle off the rug. But you
mustn’t touch the bottle with any part of your body or anything else. And not a drop of beer must be spilled.
(Answer: to roll the rug carefully)
Day 7 What is the missing letter? H, Z, X, O, I, S
(Answer: N – all these letters look exactly the same when viewed upside down)
Day 8 To create a metaphor for: “Sacriice on a beach”
Day 9 Consider the letters: H, I, J, K, L, M, N, O. These letters represent one word. What is the word?
(Answer: Water [“H to O” - H2

3. Results
In total, 163 reports were received: 81 from the lucid dream-
ers (averaging 9.0 per participant) and 82 from the control
group (averaging 9.1 per participant). Three reports were
discarded: one lucid dreamer indicated that he solved a
logical task while memorising it before sleeping, while two
other participants (one lucid dreamer and one non-lucid
dreamer) reported that they already knew the answer to
the task given. Therefore 160 protocols (79 from the lucid
dreamers and 81 from the control group) were used in the
analysis.
3.1. Logical tasks
Seventy-seven reports (39 from the lucid dreamers, 38 from
the control participants) were received in response to the
logical tasks. Only 13 answers (16.9%) provided by the par-
ticipants were correct (7 in the control group and 6 in the
lucid dreamers group). There was no signiicant difference in
the percentage correct between the two groups (18.4% and
15.4% of answers were correct, respectively; χ2
(1) = 0.126,
p = .722). Dream ‘guide’ igures provided only one correct
answer out of 11 dreams in which such guides were en-
countered (9.1%). This proportion of correct answers seems
to be somewhat lower than the rest of the answers provid-
ed by the lucid dreamers (5 out of 28, 17.9%), but these
differences were not signiicant (p = .655). Other dream
characters, that did not identify themselves as guides, pro-
vided one correct answer out of 6 dreams in which only
non-guide characters were encountered. In total, there-
fore, dream characters gave 2 correct answers out of 17
dreams in which such characters appeared (either guide or
non-guide). This percentage (11.8%) again was only about
half the proportion of the correct answers provided by non-
dream characters, i.e. by the participants themselves, (4 out
of 22, 22.2%), but the differences were also not signiicant
(p = .679).
Interestingly, after a night with a lucid dream the lucid
dreamers seemed to provide a lower number of correct
answers than after a night without a lucid dream (8.3%
vs. 26.6%), though these differences were not signiicant
(p = .180). The answers to the logical tasks are presented
in Table 2.
It is perhaps notable that both correct answers provided
in lucid dreams for the logical tasks were to the same prob-
lem (Day 7) and were the only correct answers to this prob-
lem across both groups. However one participant already
had an idea about this answer, while in the second case, the
answer was provided even without asking the question of
the dream character:
I’m back at the school. There’s a woman working with
one of the kids in the class that I work in. The woman
doesn’t look particularly old or young, maybe in her 40s
or 50s, but she’s very beautiful. I ask her if she’s a guru
and she nods. “What’s the missing letter?” I say, “H, X
. . . No, Z comes irst, H, Z, X, O, I, S?” I simultaneously
write the letters on the desk with my inger and they lin-
ger and glow. I realize that she’s looking at them upside
down, which might actually help her if my idea about the
puzzle is correct. I hope that I didn’t confuse her by say-
ing X before Z at irst. “What’s the missing letter?” She
mumbles some stuff, mostly to herself and then tells me
an answer that doesn’t make sense. “I think it has to be a
letter,” I say. She looks scared, like I’ve found her out for
not knowing the answer. “N,” she says. That’s the answer
I was just thinking of! I know that she took it from me. It’s
the answer I thought of when I was falling asleep. I’m an-
noyed. (Participant L7)
I managed to make a lucid dream but totally forgot to ask
for an answer. So it had nothing to do with the problem
to solve. Only after the dream I realized that one of the
dream characters told me several times his name is “N”.

3.2. Metaphor tasks
In response to the metaphor tasks, 40 reports were received
from the lucid dreamers and 43 protocols from the control
group (83 protocols in total). The answers to the metaphor

tasks were evaluated (ranked) by two blinded judges. How-
ever rankings of the two judges were only weakly correlat-
ed (Table 3). Originality had the highest level of agreement
(rho = .484, p < .001). Agreement for validity was somewhat
lower (rho = .278, p < .01), while agreements on overall eval-
uation, elegance and aptness, although low, were still sta-
tistically signiicant (rho = .248, .225 and .211, respectively,
p < .05). Both judges reported their dificulty in evaluating
the metaphors. Because of the differences in the evalua-
tions made by the two judges, the evaluations of each were
analysed separately (average ranks were not calculated).
Some examples of the metaphors provided by the partici-
pants that both judges agreed were good: ‘a condom in the
hands of a nun’ (for ‘lighthouse in a desert’), ‘a conveyor belt
of wealth’ (for ‘banknote loating in a river’), ‘ignorance is
bliss’ and ‘a lower growing on waste land’ (for ‘child playing
in a cemetery’), ‘Poseidon is calm and understanding’ (for
‘sacriice on a beach’), and ‘an active mind trapped inside
someone who is unable to communicate’ (for ‘a well in an
abandoned village’).
The evaluations of answers to the metaphor tasks pro-
vided by the judges are presented in Table 4.
In general, the control group achieved slightly better (low-
er) rankings for the metaphor tasks than the lucid dreamers
(Figure 1). The second judge rated their metaphors as more
apt (M = 7.33 vs. 10.40, z = -2.917, p < .01)1
, more valid
(M = 7.42 vs. 10.30, z = -2.734, p < .01)2
and more elegant
(M = 7.77 vs. 9.93, z = -2.045, p < .05)3
. However there were
no differences on these criteria according to the irst judge.
There were no signiicant differences in the rankings given
to the two groups on overall evaluation or on originality.
Despite the fact that dream ‘guide’ igures provided only
ive answers to the metaphor tasks, their answers were sig-
niicantly better than other answers of the lucid dreamers,
according to the irst judge (M = 4.00 vs. 9.60, z = -2.234,
p < .05)4
and their answers were considered to be more
valid according to the second judge (M = 6.40 vs. 10.86,
z = -2.111, p < .05)5
(Figure 2). There were also near-sig-

niicant indications that the answers of the dream ‘guides’
may be more valid (M = 4.80 vs. 9.34, z = -1.824, p = .068)6
and more original (M = 5.40 vs. 9.63, z = -1.681, p = .093)7
according to the irst judge and to be more apt (M = 7.20
vs. 10.86, z = -1.783, p = .075)8
according to the second
judge. According to the irst judge, the answers provided
by the dream ‘guides’ surpassed the answers of the control
group on overall evaluation (M = 4.00 vs. 8.72, z = -2.216,
p < .05)9
and also indicated a non-signiicant tendency for
the answers of dream ‘guides’ to be more valid than the
answers of the control group (M = 4.80 vs. 8.86, z = -1.877,
p = .060)10
.
Three answers to the metaphor tasks in the dreams of
the lucid dreamers were provided by dream characters who
did not claim to be dream ‘guides’. Comparing all answers
provided by dream characters with the rest of answers of
the lucid dreamers (Figure 3), the dream characters’ an-
swers were better on overall evaluation according to the
irst judge (M = 4.88 vs. 9.91, z = -2.423, p < .05)11
with
trends also towards better scoring on all other criteria ac-
cording to the same judge (originality12
: M = 6.13 vs. 9.84,
z = -1.830, p = .067; aptness13
: M = 5.75 vs. 9.50,
z = -1.846, p = .065; validity14
: M = 6.13 vs. 9.44, z = -1.660,
p = .097; elegance15
: M = 5.63 vs. 9.81, z = -1.915, p =
.055). There was also a tendency for the dream characters’
answers to be more original according to the second judge
(M = 6.00 vs. 9.69, z = -1.846, p = .065)16
. According to
the irst judge, the dream characters also provided bet-
ter answers to the metaphor tasks than the control group
(M = 4.88 vs. 8.72, z = -2.221, p < .05)17
with non-signii-
cant tendencies also for their answers also to be more apt
(M = 5.75 vs. 8.86, z = -1.752, p = .080)18
and more elegant
(M = 5.63 vs. 8.65, z = -1.830, p = .067)19
.
In contrast to the results from the logical tasks, the occur-
rence of a lucid dream did contribute in accomplishing the
metaphor tasks (Figure 4). The irst judge rated lucid dream
answers generally better than non-lucid dream answers
(M = 6.86 vs. 11.16, z = -2.443, p < .05)20
, as well as more
apt (M = 7.10 vs. 10.58, z = -2.008, p < .05)21
, and more valid
(M = 6.76 vs. 11.00, z = -2.415, p < .05)22
. Results from this
judge also indicate a non-signiicant tendency for greater
elegance in the answers from lucid dream nights compared
with non-lucid dream nights (M = 7.38 vs. 10.74, z = -1.955,
p =.051)23
.
3.3. Feedback
Feedback was received from eight lucid dreamers and six
control participants. In their feedback, some lucid dreamers
admitted that they were not expecting much from dream
characters before the study but subsequently discovered
that they are capable of more:
Not only did I learn that dream characters can be quite
unpredictable when you approach them with a question,
but they can be very deep and relective in their answers
as well. (Participant L3)
I wasn’t expecting them to say anything of the kind or to
act like that, so after the experiment discovered I can get
far more info than I actually thought from dream charac-
ters. (Participant L6)
However some participants retained a sceptical attitude
regarding the abilities of dream characters:
I also found that the answers given to me by characters
in my dreams were no more insightful than what I could
come up with myself. But perhaps this had to do more
with my beliefs that characters in my dreams only know
what I know. Maybe others who have more spiritual at-
titudes about their dreams would receive answers that
they hadn’t previously thought of because of their belief.
(Participant L7)
Two lucid dreamers were not able to induce a lucid dream
during the period of study and both of them admitted the
lack of motivation to solve puzzles:
I did not feel interested in the puzzles … It would be
more interesting if the puzzles would have been things
that I really care to ind an answer. (Participant L10)
Lucid dreamers are more motivated to go on adventure
then solve a task puzzle … let them go on adventure, cre-
ate landscapes or let them go back to their childhood to
ix things. (Participant L5)
Interestingly enough, on the very next night after the study
ended, one of these participants had two lucid dreams.
One lucid dreamer noted that sometimes the answers
manifested themselves in non-lucid dreams while trying to
induce a lucid dream:
It was not surprising to me that I could indirectly solve a
problem in a lucid dream by asking a dream character for
the answer … What was surprising to me is the notion of
having a problem statement, briely thinking about it and
memorizing it, and then having that problems’ answer
manifest in a non-lucid dream. I had several of these. This
is a very speciic and unusual sort of dream incubation.
(Participant L8)
The lucid dreamers also admitted a dificulty in memoriz-
ing the task without trying to solve it. Also, although detailed
data on sleep disturbance was not collected, some partici-
pants in the control group found that their engagement in
the study had disturbed their sleep – they woke up more
often in the night during the period of study.
4. Discussion
Taken together, these preliminary indings provide some evi-
dence that lucid dreams may contribute to problem solving
when dealing with more creative rather than logical tasks.
Dream characters, and especially the ones who acknowl-
edged themselves as ‘guides’, can also provide credible
advice relating to more creative tasks. This suggested dif-
ference between more creative and more logical tasks to
some extent resembles Tholey’s (1989) indings: in his study
dream characters were also more successful with creative
tasks but struggled when doing arithmetic which required
rather logical thinking. Lucid dreaming is generally con-
sidered to be a REM phenomenon (cf. Erlacher & Schredl,
2008) and it is plausible that during REM sleep associations
are made more loosely and creatively (cf. Cai et al, 2009;
Stickgold et al, 1999). Some authors (e.g. Green & McCreery,
1994; Piller, 2009) speculate that the right hemisphere might
be predominant in lucid dreams and the right hemisphere
also seems to activate a broader range of verbal associa-
tions than the left hemisphere, including alternate meanings
of ambiguous words (Faust & Lavidor, 2003). Furthermore,
creative performance and the experience of insight are also

linked with right hemispheric activity (cf. Bowden & Jung-
Beeman, 2003; Jung-Beeman et al, 2004; Martindale et al,
1984). However further evidence from neuroimaging studies
is needed, also considering that differences in the lateralisa-
tion of brain function exist between men and women, left-
handers and right-handers, and other groups (for an over-
view on brain lateralisation see: Toga & Thompson, 2003).
The lucid dreamers found their dream characters to be
far more profound than they were expecting them to be,
despite the fact that expectations themselves play a crucial
role in lucid dreaming (cf. LaBerge, 1985; Waggoner, 2009)
and observed that they can beneit from their interactions
with dream characters. McNamara et al (2005) found that
social interactions in dreams are more frequent than in wak-
ing life and the authors even suggest that dreaming might
be specialised for stimulating social interactions. However,
interestingly enough, lucid dreams usually have fewer dream
characters and fewer friendly verbal interactions than non-
lucid dreams (Gackenbach, 1988).
The exploratory approach employed in this study had sev-
eral limitations and revealed some methodological consid-
erations that need to be addressed in future studies. Firstly,
this study was conducted as a ield experiment. Although
some precautions were taken (e.g. tasks were sent after 9
pm, the participants were asked to follow the protocol pre-
cisely, not to discuss the tasks with anyone else, etc.), it was
impossible to ensure that the participants were following the
protocol as expected. Therefore it would be more appropri-
ate to conduct the study in a sleep laboratory.
Secondly, although the groups were matched by their
demographic parameters, they were not matched by their
creative and problem-solving abilities. Differences in per-
sonality factors may also have an impact, as lucid dreamers
generally seem to be more open to new experience, more
creative and with a higher “need for cognition” (Blagrove
& Hartnell, 2000; Schredl & Erlacher, 2004). The relatively
small sample size in this study was another major restriction
(e.g. only ive answers to the metaphor tasks were obtained
from the dream guide igures) which limits the statistical
power of many of the analyses.
Thirdly, the tasks themselves were complicated. Partici-
pants were able to solve a logical puzzle in only one case
out of six and, as Barrett (2007) suggests, such brainteas-
ers may be beyond the ability of many people. Another ap-
proach might be to use some personal problems that are
relevant to the participants in order to assess their problem
solving abilities, although it would be dificult to evaluate
their solutions on an objective basis. The assessment of
creativity was another issue: the judges experienced dif-
iculties when evaluating the metaphors and their assess-
ments diverged. The images given for the metaphor tasks
were fairly ambiguous and it might be that the judges were
seeing and emphasising different aspects. Therefore some
initial training for the judges on the assessment of creativ-
ity might be useful, ensuring that they are evaluating meta-
phors in the same manner. In future studies it may also be
advisable to use a larger number of judges.
Fourthly, language was another issue. Not all participants
in this study were native English speakers. Some logical
tasks were language-speciic (e.g. the tasks for days 1, 2
and 9) and the situation was even more complicated for
those lucid dreamers who were able to engage in dialogues
with dream characters since these participants reported that
they were using their native language or a mixture of their
native language and English. In some cases this completely
distorted the tasks. In one case a dream character even an-
swered: “I don’t know, it’s in English”! The metaphors used
might also lose their subtle meaning when translated into
another language. Therefore it would be much more ap-
propriate to avoid using any language speciic tasks or to
provide all tasks in the native language of the participant.
Finally, spreading the study over a longer period (e. g. pro-
viding one task every two or three days) might be preferable,
as was suggested by some participants. This might help to
increase the motivation of participants and provide fewer
disturbances to their daily life and their sleeping pattern.
To summarise, this exploratory study demonstrated the
feasibility of creative problem solving in lucid dreams and
revealed various methodological considerations that should
be addressed in future studies. The preliminary indings
suggest that lucid dreams can contribute to problem solv-
ing when dealing with more creative tasks and dream char-
acters can provide plausible creative advice to the dreamer.
Future studies should verify these indings in more con-
trolled conditions and explore further links between REM
sleep, lucid dreams and creativity. Brain imaging studies
exploring creative performance during REM lucid dreams
would be of particular interest.
