The Different Stages of Sleep

Imagine yourself falling asleep. At first you slowly fall into a light sleep, then you sink into a deep sleep. You experience sleep cycles comprised of two broad categories: REM (Rapid Eye Movement) sleep and non-REM sleep. REM sleep is known to be the dream phase, while non-REM sleep is divided into three stages: light sleep, deep sleep, and very deep sleep. Each of these phases has its own fascinating characteristics.
