PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -The phase of sleep in which most dreams occur. During REM sleep, a person’s brain activity, breathing, heart rate, and blood pressure increase, and the eyes move rapidly while closed. The muscles in the arms and legs become temporarily unable to move.

Detailed explanation-2: -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-3: -Scientists agree that sleep is essential to health, and while stages 1 to 4 and REM sleep are all important, deep sleep is the most essential of all for feeling rested and staying healthy.

Detailed explanation-4: -There is now a consensus that dreaming may occur throughout the night during both REM and non-REM sleep; however, disagreement persists over whether dreaming in these distinct phases can be said to be qualitatively different.

Detailed explanation-5: -REM Stage R Phasic REM sleep contains bursts of rapid eye movements, while tonic REM sleep does not. Stage R occurs about 90 minutes after you fall asleep, and is the primary “dreaming” stage of sleep.
