ANS: D
REM sleep usually occurs after about 90 minutes of NREM sleep; during this stage, electroencephalogram (EEG) patterns are similar to those of waking, heart and respiratory rates are irregular, muscles are flaccid, and eye movements are rapid and associated with dreaming. REM sleep periods become longer as sleep progresses and the person becomes more rested.

The sleep cycle is the sequence of sleep beginning with the sequential stages of NREM sleep, a return to stage 3 and then stage 2, followed by the first REM stage. A sleep cycle is usually 70 to 90 minutes in duration, and the typical sleep passes through four to six cycles during a 7- to 8-hour sleep period.
