i saw that about Spielberg. wonder if there's any truth to that? still haven't seen it but my curiosity is piqued even though I already read the movie spoiler. people are saying they couldn't sleep after seeing it.
somewhat related, my mother called me several weeks ago and said she was awakened during the night to her body bouncing on her bed (she lives alone). I said it might have been caused by blood flow to the brain but she said it was so real and terrifying she was unable to go back to sleep for a few hours and even then she kept the bedroom lights on. hasn't happened again. night terrors? sleep apnea? whatever it was it doesn't sound pleasant. i had a similar experience when i was younger but mine seemed to happen when i'd sleep on my back. i'd wake up to the feeling that something was pushing me down and no matter how hard i tried to get up i couldn't. very scary.
On wikipedia, after that statement about Spielberg, there's numbers for references where they cited that information from. There were two for that story in particular. One was from an LA times article and I don't remember the other but it was another valid news/entertainment source. I looked at the articles and one of them went a little bit more in detail. It said it was his bedroom door that locked from the inside and he had to call a locksmith to open it. Pretty freaky... and kinda cool. I've read mixed reviews on the movie, some are saying it's over hyped but still makes your skin crawl at times. Either way, it's probably a lot better and more effective in inducing fear than any other recent horror film [garbage] put out. I like how the movie's method is not in over-the-top blood and gore, but in the mood/atmosphere... Movies are always better that way.
Who knows what was up with your mother's story, but for yours (the feeling where you felt like you were being held down)... That's a fairly common night terror to have. I've never experienced it, but heard about it countless time and I've seen it discussed here on the forums before. There's a psychological/physiological reason for why it happens, but I don't recall exactly what that is.
