Am I being plagued by a demon? [no skeptics, pls!]?

Okay, this is a pretty long story. It all started years ago when I had a dream about a demon pouncing on me while I lay in bed sleeping (in the very same position I was when I awoke), and proceeded to suck out my soul through my mouth. (Geez, this all sounds so crazy, but if I wasn't so freaked out, I wouldn't write this). It all felt so real, too real, so I stopped sleeping in my bedroom and started sleeping on the pull out couch in the living room. It was okay for a while, until I had the dream again. The same demon attacked me, except this time in my "dream" the setting was my living room and when I awoke I was once again in the same position I was in when I was attacked. When all this happened I'd lived in Ga, and it always happened at 3 am. So I (seriously) wouldn't sleep at 3 am anymore, and the dreams stopped for a long time. I've long since stopped not sleeping at 3, but the dreams didn't come back- until last night. Except this time it went too far. In the dream the demon tried to disguise itself as my grandpa, the person who I am closest to and who means the world to me, but for some reason I could see through the disguise and knew it wasn't my grandpa. The demon once again attacked me, but this time I fought back and it disappeared. Except, unlike all the other times, I didn't wake up immediately after it happened. My dream continued on for some time until I awakened to the sounds of someone pressing ons on my tv (even though there was no one there). The sound stopped and when I glanced around my room I noticed my bedroom door was cracked (I always leave it shut). As I watched the door closed on its' own. That was a little over an hour ago. Also, in the past usually during plane or bus rides I have had moments where I've gone to sleep and have awaken to all the pengers either openly staring at me or shooting nervous glances in my direction. The last time this happened, I pretended to go to sleep again only to hear the penger behind me say to his neighbor, "Why the hell did she just do that?" and when I glanced around I found him and the other pengers staring at me. The only thing I remember is falling asleep... that's it. I have no idea what's going on or what's happening to me. I haven't told anyone, because I was afraid they'd think I was crazy (like alot of you probably do now...). If anyone can help me understand what's going on or point me in the direction of someone who can help me, I'd greatly appreciate it. Thanks so much!
