REM sleep may be the most fascinating and well-studied phase of sleep. Non-REM refers to the minimal eye movements of the first three stages of sleep, while #REM refers to the rapid eye movements characteristic of the fourth and final stage of sleep.

Our understanding of sleep and dreams took a significant step forward with the discovery of rapid eye movement sleep in 1951. Researchers discovered that not only do the eyes move during #REMsleep, but the brain is nearly as active as it is while awake. Marked shifts occur in the brain and body during REM, heralding a stage entirely unlike the other three stages of sleep.
