I'm glad I stumbled on this thread. I've been trying to come up with a way to convince my BF that what he's seeing in his sleep are not demons out to get him. I'm going to relate his experience from a few weeks ago.
He was in bed beside me fast asleep and all of a sudden, he just started shaking and moaning. This happens a lot...he gets nightmares. I always wake him up when it doesn't seem like he can wake himself.
Anyway, he woke up with a start and was panting...very afraid! Then he got up and started rifling through the closet, turning lights on, just really freaked out. So I asked him what was happening. He said "You didn't see them??". I said "Who?".
It was then that he told me that he had walked into the bedroom from the kitchen and saw himself lying in bed next to me sleeping...and that these 8-foot-tall black shadowy creatures were hovering over him. He said he was standing there yelling at them to get away from his body, but they wouldn't leave. They just kept getting closer and closer and he was afraid they were trying to possess him and steal his body. He said "You didn't hear me yelling?". I told him he was sleeping. He said "No, I was in the kitchen!".
As much as I tried being the voice of reason and explaining that these things don't exist, he was petrified. He slept with the bathroom light on for weeks. He really is convinced that these are demons. I tried being analytical and using a bit of "maybe it's your past and your guilt coming back to haunt you in your dreams" psychology. Kind of metaphorical... But he still believes they're real creatures. It actually scares me to see him go from being the strong-minded, amazing, brave man that he is...to a quivering ball of goo...all because of a superstition that he was raised with.
Now, he's seen these shadowy figures since he was a kid. He said his grandmother saw them as well. I can't explain how they BOTH saw them, but it seems like perhaps he may not remember overhearing her talking about them and then he started having sleep paralysis and started seeing them himself?
