.How often does sleep paralysis happen to any of you? 7 out of 10 times if I sleep on my back im likely to have it. It all started when i was around 11 or 12, I was sleeping on the floor of my parents room and awoke feeling someone standing on my back. I actually felt that i could knock them off if I wanted to but was way too scared. over the years ive had it but only sparringly but as i got older and older they happend more often and they became more intense. The incident when i was 11 was the first time i felt someone standing on me, but after that it was that I just could not move. But now whenever it happens I feel that there is something ominus in the room with me that wants to take over my body. I become terrified when this happens and I try to force myself to move eventaully shaking myself out of it. Sometimes I feel hands over me holding me down but when I awake a pillow or the sheets are where I believed the hands to be. It seems like im maybe kinda dreaming when it happens or hallucinating , do any of you guys have any experiences like this happen to you?
