Explanation: 

Detailed explanation-1: -REM sleep happens about an hour to an hour and a half after falling asleep. REM sleep is when you tend to have vivid dreams.

Detailed explanation-2: -REM Stage R Stage R occurs about 90 minutes after you fall asleep, and is the primary “dreaming” stage of sleep.

Detailed explanation-3: -Most of your dreaming occurs during REM sleep, although some can also occur in non-REM sleep. Your arm and leg muscles become temporarily paralyzed, which prevents you from acting out your dreams. As you age, you sleep less of your time in REM sleep. Memory consolidation most likely requires both non-REM and REM sleep.

Detailed explanation-4: -A majority of your dreams take place during REM sleep. However, REM is not the only stage in which dreams occur-that’s actually a common myth about sleep. That said, the dreams you experience in REM sleep are usually more vivid than non-REM sleep dreams.

Detailed explanation-5: -Age: Time in each stage changes dramatically over a person’s life. Newborns spend far more time in REM sleep and may enter a REM stage as soon as they fall asleep. As they get older, their sleep becomes similar to that of adults.
