REM Atonia

The shutting down of neurotransmitters in the motor system, preventing a sleeping person from acting out their dreams. Often confused with Sleep Paralysis. REM Antonia only occurs during the REM phase of sleep, and happens every night for people without any REM disorders.

Sleep paralysis happens while in NREM (as a very rare occurrence in a select few individuals), whereas REM Atonia happens while in REM sleep (Rapid Eye Movement)

REM behavior disorder results when an individual does not experience REM Atonia, causing them to act out their dreams. This differs from sleepwalking, which takes place during NREM sleep.
