Which sleep stage accounts for about 20-25% of sleep in a typical adult night?

Explanation:
REM sleep is the stage that typically makes up about 20-25% of an adult night. During REM, brain activity resembles wakefulness, dream activity is common, and the body experiences muscle atonia. Sleep occurs in roughly 90-minute cycles, and REM periods tend to get longer as the night goes on, so a healthy adult usually spends about a quarter of total sleep in REM. In contrast, the early-night sleep features more non-REM deep sleep, while lighter non-REM sleep (N1) is brief and N2 comprises the largest portion overall. So the 20-25% figure best matches REM sleep.
