PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -REM sleep is thought to play an important role in memory and learning. During normal sleep, a person goes through four to five sleep cycles that last about 90 minutes each and include both REM sleep and non-REM sleep (light to deep sleep). Also called rapid eye movement sleep.

Detailed explanation-2: -REM is the Rapid Eye Movement sleep stage when your brain is as active as it is during the awake state. Though you are sleeping and your eyes are closed, your eyes dart from side to side beneath your eyelids during REM sleep. This led to the name “Rapid Eye Movement (REM)” sleep.

Detailed explanation-3: -During the night, you cycle through two types of sleep: non-rapid eye movement (non-REM) sleep and rapid eye movement (REM) sleep.

Detailed explanation-4: -REM sleep – named for the rapid eye movements associated with it – has been known since the 1950s to be the phase of sleep when dreams occur. But the purpose of the eye movements has remained a matter of much mystery and debate.

Detailed explanation-5: -Rapid eye movements (REMs) represent a peculiar feature of REM sleep. They episodically occur mostly grouped in bursts and correspond to rapid saccades, similar to those occurring in the awake state when visual inputs are absent but imagined [1].
