Detailed explanation-1: -During REM sleep, your eyes move around rapidly in a range of directions, but don’t send any visual information to your brain.
Detailed explanation-2: -REM sleep, in full rapid eye movement sleep, one of two phases in the sleep cycle, in which a person experiences dreams, atonia (reduced muscle tone), irregular closed eye movements, and elevated levels of brain activity.
Detailed explanation-3: -When our eyes move during REM sleep, we’re gazing at things in the dream world our brains have created, according to a new study by researchers at UC San Francisco. The findings shed light not only into how we dream, but also into how our imaginations work.
Detailed explanation-4: -Nerve pathways in the brain that prevent muscles from moving are active during normal REM or dreaming sleep, resulting in temporary paralysis of your body. In REM sleep behavior disorder, these pathways no longer work and you may physically act out your dreams.
Detailed explanation-5: -Stage 2: This period of light sleep features periods of muscle tone (muscles partially contracting) mixed with periods of muscle relaxation. Your eye movement stops, heart rate slows and body temperature decreases. Brain waves become slower.
