What Happens With Hypnagogic Sleep Paralysis?

while you fall asleep, your body slowly relaxes. Usually you wont know whats happening, so you do not notice or see the change. However, if you remain or become aware while you fall asleep, you may not move or speak. During sleep, your body changes between REM or, rapid eye movement, and also NREM, non-rapid eye movement, sleep. One cycle of REM and NREM sleep could lasts atleast about 90 minutes. First thing that occurs first is NREM and it takes up to 75% of your overall sleep time. While you are in NREM your body relaxes and it stores itself. After NREM happens, your sleep switch to REM. Your eyes will move quickly and thats when dreams occur, but the rest of your body remains very calmed. Your muscles are going to remain calm or "turned off" means that you wont be able to move your body during REM sleep. If you become realized or wake up before the REM cycle has finished, you may notice that you cannot move or speak.
