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: -90% of dreams occur in REM sleep, dreams are normally more vivid than non-REM dreams. Emotionally stressful days lead to increased REM sleep.
Detailed explanation-3: -During REM sleep, brain activity increases, voluntary muscles are inhibited, and rapid eye movements and dreams occur (McCarley et al., 1995).
Detailed explanation-4: -The REM phase is also known as paradoxical sleep (PS) and sometimes desynchronized sleep or dreamy sleep, because of physiological similarities to waking states including rapid, low-voltage desynchronized brain waves.
Detailed explanation-5: -While you rest, your body goes through different stages of the sleep cycle. Deep sleep, for example, is the stage of sleep you need to feel refreshed when you wake up in the morning. Unlike rapid eye movement (REM) sleep, deep sleep is when your body and brain waves slow down.
