sleep paralysis/night hags

It seems so scary to me. Thank god I never experience that (touching wood). I have heard from people around me telling me their friend's similar experience. They usually concluded such phenomena as paranormal. But after reading your scientific explanation, it's much more relieving. Hallucination can be very scary. Matrix movie had told us the concept . Besides, if you are gamers, you will know how imagination and virtual reality is very realistic sometimes especially when we are too obsessed.

I usually experience this when I am stressed-out, it is really frightening. I can sense/see my surroundings but it's as though I am in a body-bind. And yes, there's usually a dark shadow, which creeps me out even more (I get afraid to fall asleep after). And there are strange noises (whispering, I think).

I experience it a lot of times especially back in college. Other people actually say it's a paranormal event but yeah, your explanation pretty much sums up the scientific side. there came a time also the i was so used to it that i anticipated it already everytime i go to bed - and it does happen, and i know when will it happen. Its when i have this unique feeling that - oh yeah - here we go again. Sometimes i actually enjoy the experience and try some stuff like - try moving my leg or hands or head.Sometimes i can come out of it at will. These are the times the "hag" or the shadowy figure is not present. But of course, when there is the dark figure, it really is scary and you can't help but think that there's some kind of evil force preventing you from moving; even suffocating you.
