There are several stages of sleep including stages 1 through 4 and REM sleep. REM sleep is characterized by rapid eye movement and increased physiological arousal like heart rate and breathing despite the body being paralyzed. Dreams commonly occur during REM sleep. Theories about the function and meaning of dreams include that they represent unconscious wishes, allow for information processing during sleep, or are random neural activations assembled into a narrative. Sleep disturbances can include insomnia, sleep apnea, sudden infant death syndrome, narcolepsy, and sleepwalking. Circadian rhythms regulate biological cycles over 24 hours and impact conditions like seasonal affective disorder and jet lag.

Dreams are what gives us strength each day to continue what we love doing.
We must think of the kind of lifestyle we promised ourselves before we feel like giving up

Sleep is defined as unconsciousness from which the person can be aroused by sensory or other
stimuli.
distinguished from coma, which is unconsciousness from which the person cannot be
aroused. There are multiple stages of sleep, from very light sleep to very deep sleep; sleep
researchers also divide sleep into two entirely different types of sleep that have different qualities,
Sleep-wake cycle refers to our 24 hour daily sleep pattern which consists of
approximately 16 hours of daytime wakefulness and 8 hours of night-time sleep.
The complex process of the sleep-wake cycle is controlled by the body’s circadian rhythm and sleep homeostasis (the amount of accumulated sleep need that builds during time spent awake).
