These are more than Paralyzed Dreams (please help)!!!?

I don't know why this keeps happening to me what could I have done that was so bad. I'm 16 years old and I've been having these dreams since i was 13 and i still have know clue why they keep happening. I haven't had one of these nightmares in months but they always manage to sneak up on me. I'm not crazy i don't think they are just dreams i think they mean something. Last night while i was sleeping i felt like i woke up but I couldn't move , I felt my blanket wrap around my left leg then my right then it covered my face so i couldn't see. It pulled my leg like it was trying to pull me in my closet , i tried to move my hands but they we're paralyzed. By that point i wanted to panic but ive had these dreams so many times i knew the only thing i could do was say a prayer. Soon after that the blanket was ripped off my face and i felt something inches from my face and it had so much heat that the side of my face was hot. All of a sudden I woke up in the same position i fell asleep i looked at my closet cause for some reason i felt like something was in there. I just wanna know what you think is happening i cant deal with this anymore they dreams are getting more and more real to the point where i feel like something is trying to get me. My parents think its nothing i have no where to turn!!!!
