I'm pretty freaked out at the moment. Ever see the movie Groundhog Day, where Bill Murray kept reliving the same day over and over again no matter what he tried? I just had a nightmare like that. I was trying to get out of bed to get a glass of water, but couldn't. The covers were smothering me, I'd get tangled up in them, and no matter what I tried, I'd "wake-up" again in bed with the covers back over me. Once I made it to the kitchen but when I tried to drink, the water would run out of the glass but never make it my mouth. It felt so real, I thought it was a hallucination and was going to call 911 but never made it to the phone. Then finally on one attempt to escape from my bedroom, I prayed to God to please help me. When I made it to the bedroom door I realized it wasn't my door and I turned back to bed and asked God for help again then just let myself fall, but instead of falling, I floated to the ground like you would in a cartoon and when I woke up he next time, I really woke up and jumped up and turned on my light and got a glass of water. Now I'm afraid to go back to bed.
Reading on WebMD, it sounds like Sleep Paralysis. Putting a name to it doesn't make me feel any better though. Or like going back to bed.
