In the second stage, you progress to a deeper and more relaxed sleep. Your brain waves slow way down and are less responsive to external noises and interruptions. In this super deep phase of sleep, your muscles are paralyzed while your eyes move rapidly behind your eyelids.

Your brain actually becomes more active during REM sleep, and many people have vivid dreams in this stage. Your heart rate and breathing speed up.

Your body typically goes into REM sleep about 90 minutes after you fall asleep, and it can last for up to an hour. Interestingly, babies and children spend more time in REM sleep than adults do.
