I couldn't move and there was this weird weight on my chest holding me down.
Sleep paralysis is also called "Old Hag Syndrom" for that reason: because someone who suffers sleep paralysis has the feeling that there's an old witch sitting on his chest preventing him from moving.
Being awake but unable to move is a scary thing when you know you CAN move but can't.
Sleep paralysis is actually the cause of your brain not activating certain functions when they should be activated. When you go to sleep, your brain shuts off your muscle response, so that you won't move in your sleep, to prevent you from awakening, or injuring yourself by moving while dreaming. However, when your consciousness wakes up, sometimes the brain forgets to turn on muscle response again. The result is a mind awake/body asleep state very similar to trance, but far less benign.
This state is always accompanied by a feeling of dread or fear. I remember every time I had sleep paralysis, it felt like something was coming up the stairs, or opening the door, or even right there in the room with me. Note that I use 'something' rather than 'someone'. It's not the fear of a burglar or thief you feel, it's the terror of something not of this world. I have no idea how or why the brain sends such fearful input, but the fact is, and most sleep paralysis sufferers can attest, the terror you feel, coupled with the paralysis, is one of the most terrifying things a person can feel.
I've had loads of sleep paralysis 'attacks', and by now I realize what's going on when I wake up and can't move. But even when I tell myself, "It's only sleep paralysis!", there's still that awful feeling. Last time was a few days ago, and my girlfriend was sleeping next to me. I tried to make sound, get her to wake me up, but all I could manage was a feeble wheeze, even though I tried frantically.
Sleep paralysis, by the way, usually happens to people who are tired and have sleeping problems, but try to sleep anyway, so they have this drifting-in-and-out kind of sleep.
Any of you ever had false awakenings? They're even creepier, in a way. Basically, you wake up, get out of bed, get dressed, do everything you normally do, but something feels
wrong. You can't pinpoint what it is, but something's just
not right.
Last time I had it, I got up, took a shower, got dressed, did everything I always do when I wake up, but when I opened the curtains, the street was totally empty. There were no cars, no people, just dead asphalt and empty buildings. That was pretty creepy. The time before, same thing happened, only then it was night, and when I opened the curtain, I saw a bright stripe of fire on the horizon and I knew that the bombs were falling.
You always wake up for real afterwards, but it takes a few hours to actually convince yourself that this is the real world. They're not like nightmares, because false awakeningq actually let you live through each moment consciously and rationally. Freaky.
