R.E.M.

R.E.M. stands for Rapid Eye Movement, which is a stage of sleep characterized by quick movements of the eyes, increased brain activity, and vivid dreaming. This phase typically occurs several times during a sleep cycle and plays a crucial role in memory consolidation and emotional processing. During R.E.M. sleep, the body is generally paralyzed to prevent individuals from acting out their dreams. It is considered essential for overall health, as it contributes to cognitive function and emotional well-being. Adults usually experience about 20-25% of their sleep time in the R.E.M. stage.
