Dreamt about a Demon?

So I'm actually really new here and I absolutely have no idea on anything about the paranormal world. I was just a bit freaked out by this dream. Okay, maybe a little more than freaked out since I did just signed up for some random website.

Okay, so the dream started pretty weirdly, I'm pretty sure I dreamt it before. Like my little cousin was playing with marbles and it scattered everywhere. In the first dream though, I just gathered it up and continued to watch my cousin, but this time a man came up. He didn't look weird or anything, just an ordinary man. But I've never seem him before in my life, and somehow in my dream something kept shouting "run, you're not safe". I wanted to follow the advice but the man kept staring and I couldn't move.

The man told my cousin to sit down on the couch and he followed. Then he told me to pick up the marbles and I followed too. As I did he just sat down by this old mirror we have at our house and watched me. But then there was a couple of marbles just by him, so I went to get them, but just as I reached over him for the marbles, I felt his breath on the side of my face. It was weird, because when I was young and I had nightmares, I would convince myself it's just a dream and the first thing I would do is touch something and see if my hand goes through; and when it does I immediately woke up. I can't explain why that worked, it just did.

His breath was actually disturbing me, so I tried putting my hand on his knee to know if it was real or not, and to my shock, I didn't wake up. It felt solid, and I'm one hudred percent sure that I really COULD feel his breath. I panicked a little but then (okay, this part is really weird) I felt his lips on my neck and it felt so strange. And, no, it wasn't the sloppy kind of kiss like on adult movies, his lips were just there, unmoving but definitely there.

And even stranger is that I liked it. It felt nice and just when I was enjoying it, I woke up.

And when I did, I still felt his breath on the side of my face but when I turned, I saw nothing. I checked my clock and it was 2:00 am. And I'm alone in my dorm.

I don't know what this is but I'm feeling jumpy since it happened (that was about a week ago) and I'm sort of frightened and disappointed (?) at the same time. And since that dream little odd things had been happening. The stragest so far is me getting locked in my bathroom (it sounds weird but it happened four times and it's getting creepy)

So I'm alone in my dorm, so I don't really lock the bathroom when I shower, just the door to the dorm itself. But whrn I was going to get lunch with my friends and I was just about to leave the bathroom after a shower, the door wouldn't open, I'm also pretty sure that that door couldn't lock from the outside. That happened two more times and on the most recent one (just last saturday) I was headed for a party, and I didn't feel like spending hourse of quality time with my bathroom, so I put a chair to keep the door from closing, but guess what, when I finished my shower, the door was closed and the chair wasn't even there anymore!

Like I said, I know nothing about "the other worlds" so a little help would be nice?
