Bad case off sleep paralysis

I've been having sleep paralysis since I was a kid and it's got to the point where where it doesn't scare me anymore, sometime I can move but it feels like it takes all my effort and when I get to a certain point like a door Im back at the body then the same thing happens upto seven times before I actually wake up. When I went to hospital the same dream accorded and I was walking around the hospital wards. And a time when there's been a black entity's on my chest and what I can only describe as trying aggressiv to get something out my chest but I wasn't just layed there I was throwing punches I couldn't tell weither it effected it or not but I carnt remember much after that.
