I started having sleep paralysis when I was about 22 & I'm now 54. Every time I feel something very evil in my room & I'd never heard of this or known of anyone else to have it. I started reading heaps of books on the supernatural but never found anything about this. I know that sleep paralysis can happen when you wake & your body is still asleep, but I also believe that that is not always the case. Most of the time, the first 20 or so times, I was sleeping on my side & when I'd wake I could feel another body pressed up against my back. It felt very strong & evil. One time I woke (usually happened about 2am & often around 10 mins after dosing off), paralysised & had what I believe was a demon dog sitting on my chest & frothing at the mouth. Also standing right beside me was a dark figure of a man wearing a hat. He didn't seem evil like the dog. He just seemed to stand there & not even notice me. I could see my clock from where I was laying, without needing to turn my head, which I couldn't do, & it was 2am & when the evil finally went, it was 2.10am.
I know I was fully awake & hadn't just woken from a nightmare or any other dream. Many other things happened over the 20 years it went on for but it's too much to include here.
If anyone else has felt the evil & seen demons etc., I would suggest you look at a web site called "true ghost tales-real ghost stories" & you certainly won't feel alone. I found out throught that site that the dark figure of a man that I saw was actually a 'shadow being' called the 'man in the hat' (I'd also seen him many, many times when I was a child. I would wake up & he'd be standing at the doorway just looking into the room. I wasn't paralysised then but he scared me & I'd keep very still & just watch him for ages, then finally put the sheet over my head & eventually go back to sleep. "shadow creatures aren't known to be evil & nobody really knows what they are. They just seem to want to watch people & are often seen dashing through hallways or standing in doorways.
The last time I had sleep paralysis & could feel the demons coming, I remembered a book I'd just read & it had a chapter on How to Fight Demonns Off' but all I could remember while I lay there terrified was that it said to prey for help. Being paralysised & unable to talk, I just preyed in my mind for Jesus to help me. Straight away I felt the evil leave very quickly & I haven't had sleep paralysis since & that was about 15 years ago.
Another thing I found was that it only happened when I was the only person in the room & only when my mind was completely clear. If I'd taken a pill to help me sleep or had a few drinks it never happened.
Well, I hope I haven't rattled on too much, but I really hope this can be of some help to even one person, as it's truely terrifying.
