Demonic nightmare when i was 10

when i was 10 i had a very demonic night mare about a ghost.. he looked like casper but with big bulging bloodshot eyes and he moaned at me and i swear to goodness i heard it.. i tried to throw a hairbrush at him but my arm was literrally paralyzed and then i woke up and saw a phantom shadow sitting on my bed and he was fading away as soon as i saw him.
ive been told what i seen was a poltergiest and he was trying to kill me and that its not safe for me to sleep at that home anymore.

I wont stay in that house for nuthin. its my moms house but i still go to visit her. i wont stay for too late tho, im always outa there by 10pm! thanks for your help, hopefully i will get some more posts on this!:-)
