Was it just a dream?? (possibly triggering?)

Okay this has been bothering me for a while now.
I had a dream about two months ago. It started out like any other dream but it changed into something really creepy. It felt real, like in that state where someone woke you up by sitting on the bed or something you can easily fall back to sleep after. It felt like someone was on top of me rubbing on me. I remember telling myself just pretend to be asleep. And they started to get rough like dry humping me so I kind of moved my legs to lazily push them away. They didn't fight me or anything. They got off the bed and said "I'm a monster" and I fell back to "sleep".. It's just I have trouble sometimes telling the difference from a dream and reality. But the thing that REALLY got me was I discovered two days later my window had been fixed so it appeared shut but wasn't. I NEVER do that to my window because I'm always afraid someone is going to get in. So ever since I've been back I'm been checking my window and my bedroom and putting something in front of my door. I don't know what to think about this. It's really disturbing me. I'm just thinking about all the creepy $#%^ I've seen and maybe there is actually a reason I'm terrorfied of the dark and it's not because of ghosts and demons.

Hey, __nonreality! Do you have any idea who'd want to do that to you? This is creepy, but I think a lot of people dream while they are "awake" and it seems very real. Many of them feel like something or someone is on top of them.
If you think there is good reason to belive that it happened, don't doubt yourself or your feelings. They are there for a reason. Maybe it reminded you of something else.
