The phenomena of REM:where you brain is quiet, but your body is very aroused.

Detailed explanation-1: -REM sleep is called “paradoxical” because of its similarities to wakefulness. Although the body is paralyzed, the brain acts as if it is somewhat awake, with cerebral neurons firing with the same overall intensity as in wakefulness.
Detailed explanation-2: -Paradoxical sleep (PS) is characterized by EEG activation with a disappearance of muscle tone and the occurrence of rapid eye movements (REM) in contrast to slow-wave sleep (SWS, also known as non-REM sleep) identified by the presence of delta waves.
Detailed explanation-3: -What Defines Paradoxical Sleep? The paradox is that even though the brain is quite active during REM sleep, consuming large amounts of energy, the body remains completely inactive.
Detailed explanation-4: -During paradoxical (aka REM) sleep, things get trippy. Your heart rate increases, and your body stops regulating temperature. Your brain activity is strong (as if you were awake), so you might have vivid dreams-but your body is essentially paralyzed.
