REM sleep is the last stage of each sleep cycle, and the stage in which dreaming occurs and the muscles shut down, making the body immobile.

The first stage is a partial waking stage, which happens between each sleep cycle, although normally consciousness is not fully regained.

After this stage, there are two stages of deep, restorative sleep, where hormones are released. These hormones are responsible for growth and muscle development, among other things. Deep sleep is when people will be hard, if not impossible, to wake.
