It takes about 2 hours to go through all five stages of sleep, and then they repeat. Rapid eye movement (REM) sleep usually occurs about 90 minutes after we fall asleep. Adults spend half of their sleep time in stage 2, 20 percent of the time in REM sleep, and 30 percent in the other stages. Infants start out spending about half of their sleep time in REM sleep.
