I have. I used to experience sleep paralysis in middle school. It usually happened when I woke up from a nap or fell asleep for a short time. When I experienced sleep paralysis, I was able to hear ghosts calling my name in my ear or felt them on my chest. Although I tried to get some help I could not move my body or say anything. It made me so frightened that I was even afraid of sleeping sometimes. I did not know what it was back then, but now I know that it was sleep paralysis.
Here are other people who have experienced sleep paralysis and one of explanations for sleep paralysis.
So what is sleep paralysis?
As you can guess, you feel paralyzed when you falling asleep or awakening. You can see or feel things but you simply cannot move your body or say things.
Sleep paralysis occurs in two different ways.
1. If it occurs while you are falling asleep it is called hypnagogic or predormital sleep paralysis. When you fall asleep your body normally relaxes and you become unconscious. However, if you still remain conscious you may experience sleep paralysis.
2. If it occurs while you are waking up, it's called hypnopompic or postdormital sleep paralysis.
When we sleep, we go through 5 stages of sleep. The stage one through four is considered non-REM(NREM). During these stages your body relaxes and these four stages take up the most of sleeping time. The last stage is called REM(rapid eye movements). You have more dreams at this stage as your eye move rapidly. When your body remained relaxed from NREM but enter REM and become aware before the REM cycle finishes, you may experience sleep paralysis.
What are the possible causes?
- Disruption in the sleep cycle
- Anxiety, stress
- Sleeping with your face up
- Sudden changes in lifestyle
So if you have ever experienced sleep paralysis and are afraid of it, I hope you no longer worry about it. It is very unlikely to be caused by ghosts or aliens.
Thanks for your time!
