Life is but a dream to me...

Why the fuck do I always have weird dreams. I often have dreams that are so real and scary that I find myself waking up in the middle of night very often. I often have awaken and I can't move. I feel like someone else in the room with me. Sometimes if I am laying on my back I will see a dark figure standing over top of me and I go to move or scream I can't Its like I am paralyzed and all I feel is evil in the room. I just close my eyes and ask for God to make it go away and just try to go back to sleep within a few minutes it gone and I can scream again, it's just very scary since I am not even able to move or make any kinda of noise at all. I've read that it's called sleep paralysis, but I think it's more to it than that. Also I have gone to sleep and woken up with the feeling that someone is pulling my legs off of my bed. It actually felt like my legs were off the bed in mid air and I was holding on to my sheets really tight but I still keep feeling the pulling on my legs. My body was sideways like it was being pulled. It scared the shit outta me. I hate having dreams like that, they scare me the most. I often dream of the dead as well as if they were alive, sometimes I think they are trying to talk to me through dreams. I actually will have dreams that family members will have something happen to them be it them dying or in the hospital for something serious and within days or weeks it will happen. Maybe I need to see someone about it. I don't quite understand it and why does it happen to me? I am always researching dreams online but it doesnt prove as very effective, I have a few dream books. I just wish I could make more sense of it all. They are too real and I feel like I could learn so much more about them.
