    a sleep cycle is 90 minutes bharacterized by the rapid and random movement of the eyes REM sleep normally occurs close to morning Criteria for REM sleep includes rapid eye movement, but also low muscle tone and a rapid, low-voltage EEG REM sleep in adult humans typically occupies 20–25% of total sleep, about 90–120 minutes of a night's sleep. During a normal night of sleep, humans usually experience about four or five periods of REM sleep; they are quite short at the beginning of the night and longer toward the end. Subjects' vividly recalled dreams mostly occur during REM sleep.
