Stage 5: REM sleep The rapid eye movement stage occurs about 90 minutes after you fall asleep, and is the primary “dreaming” stage of sleep. REM sleep lasts roughly 10 minutes the first time, increasing with each REM cycle. The final cycle of REM sleep usually lasts for roughly 60 minutes.
Are you asleep during REM?
