Reading the other topic about getting to sleep, it made me think of this one. Does anyone here ever wake up in the middle of the night but you can not move at all. Like I mean at all can't breathe or anything. It is terrible, I can't shout for help.. Only move my eyes around and hopelessly try to move my muscles.
This usually lasts less than a minute I'd guess but it feels like an eternity.
Finally when it does end it feels like the weight of the world was lifted off your body and you can finally move.
After that happens I usually can't fall back asleep.. most likely because I am scared it will happen again. This hasn't happened to me in like a year but I think about it before I go to sleep like this could be the night.
Can anyone relate?
I used to get this occasionally when napping during the day.
Your skeletal muscles are normally paralyzed when you are in a state of light REM sleep. This is totally normal. If fact it is what prevents you from physically acting out your dreams. It's just not normal to be
aware of the sensation of not being able to move. This scary but harmless phenomenon is caused by the mind partially waking up before the rest of your body. It can be thought of as the reverse phenomenon to sleep-walking (which occurs when your body "wakes up" while you are still dreaming).
The sensation of having a weight on your chest and/or not being able to breathe is a hallucinatory phenomenon. In a lot of places this scary sensation of suffocation is colloquially referred to as the "Old Hag". The myth is that the "Old Hag" (or a demon of sorts) sits on the paralyzed person's chest and/or strangles them. In reality this is just a frightening hallucination. You are still breathing even if you can't quite feel it.
I think it's interesting that sleep paralysis explains a lot of mythology, including out-of-body experiences and alien abductions. The worst thing I ever experienced was the sensation of my bed being pushed across the room and the sheets being pulled out from under me. I really thought there was an intruder in the house attacking me. When I finally managed to pry open my eyelids and sit my body up under the greatest effort, I saw that everything was still in tact and my bed hadn't moved an inch. Even so, it was so terrifying and seemed so real that I couldn't convince myself that I had dreamed the whole thing.
