4. Consciousness, many have argued, is what separates
humans from other animals. Consciousness refers to
our awareness of our own mental processes, such as
our thoughts, feelings, and sensations. It is possible
that we are the only beings on this planet that have
this type of self awareness or level of consciousness
and the ability to introspect, or look inward and
examine these processes. For example, if you are
angry, you can try to understand your anger, why you
are angry, what that anger feels like, etc. But can a
cat?

Segmund Freud divided human consciousness into three levels of
awareness the conscious, preconscious, and unconscious. Each of
these levels corresponds and overlaps with Freud’s ideas of the id,
ego, and superego.

10. Stages of Consciousness
Body Clocks
Many people begin the day full of energy but then start to feel run-
down by mid-afternoon. Other people struggle to plod through the
morning routine only to finally feel energetic in the evening.The daily
fluctuations of energy levels are known as the circadian rhythm and
play and important role in human consciousness. Sometimes referred
to as the body's 'clocks,' these daily rhythms have a major impact on
your consciousness as well as a wide number of physiological states.

11. Sleep and Consciousness
Sleep has fascinated researchers, scientists and
scholars for thousands of years.Technological
innovations during the last century allowed scientists to
study sleep in ways that simply weren't possible in the
past, which has helped lead to a number of theories of
sleep.

13. Dreams and Consciousness

15. WhyWe Dream
Sigmund Freud’s theory of dreams suggested that dreams
represented unconscious desires, thoughts, and motivations. According to
Freud’s psychoanalytic view of personality, people are driven by aggressive
instincts that are repressed from conscious awareness. While these thoughts
are not consciously expressed.
He also described two different components of dreams: manifest content and
latent content. Manifest content is made up of the actual images,
thoughts, and content contained within the dream while
the latentcontent represents the hidden psychological meaning of the
dream

16. Hypnosis and Consciousness
The induction of a state of consciousness in which a person
apparently loses the power of voluntary action and is highly
responsive to suggestion or direction .The hypnotist does not
hypnotize the individual. Rather, the hypnotist serves as a sort of
coach or tutor whose job is to help the person become hypnotized."
While hypnosis is often described as a state characterized by
focused attention, heightened suggestibility. People in a hypnotic
state often seem sleepy and zoned out, but in reality, they are in a
state of hyper-awareness.
