During REM sleep, your eyes move rapidly behind your closed eyes, your heart rate speeds up, and your breathing becomes irregular. In contrast to other stages of sleep, in which your brain waves slow down, your brain is highly active during REM sleep, and your brain waves become more variable.
Full Answer
Which of the following occurs during rapid eye movement (REM) sleep? The muscles are paralyzed, and body temperature, blood pressure, and heart rate and respiratory rate increase.
When you enter REM sleep, brain activity increases again, meaning sleep is not as deep. The activity levels are like when you're awake. That's why REM sleep is the stage where you'll have intense dreams. At the same time, major muscles that you normally control (such as arms and legs) can't move.

Most dreaming occurs during the fourth stage of sleep, known as rapid eye movement (REM) sleep. REM sleep is characterized by eye movement, increased respiration rate and increased brain activity. The American Sleep Foundation suggests that people spend approximately 20 percent of their total sleep in this stage.
REM Sleep. A recurring sleep stage during which vivid dreams commonly occur. Also known as paradoxical sleep, because the muscles are relaxed (except for minor twitches) but other body systems are active. Alpha Waves. The relatively slow brain waves of a relaxed, awake state.
rapid eye movement sleepREM sleep is thought to play an important role in memory and learning. During normal sleep, a person goes through four to five sleep cycles that last about 90 minutes each and include both REM sleep and non-REM sleep (light to deep sleep). Also called rapid eye movement sleep.
Sleep occurs in five stages: wake, N1, N2, N3, and REM. Stages N1 to N3 are considered non-rapid eye movement (NREM) sleep, with each stage a progressively deeper sleep. Approximately 75% of sleep is spent in the NREM stages, with the majority spent in the N2 stage.
During the very deep sleep of STAGES 3 and 4 is when sleep phenomena, such as sleepwalking, sleep talking and night terrors occur.

Rapid eye movement sleep (REM sleep or REMS) is a unique phase of sleep in mammals and birds, characterized by random rapid movement of the eyes, accompanied by low muscle tone throughout the body, and the propensity of the sleeper to dream vividly.
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.
