Quizplus · Accepted Answer

REM sleep is called paradoxical sleep because although the body is in a state of deep relaxation and reduced muscle tone, the brain is highly active and resembles the state of being awake, with rapid eye movements and dreaming. This is paradoxical because it is a combination of two seemingly contradictory states - deep sleep and wakefulness.
