Alright, this was a combination of a dream and reality I had one night.
It was the middle of the night, and I was fast asleep in my loft bed. I started to have this horrible dream. In the dream, mind you at the time I did not know this was a dream, I had just woken up and was lying in my bed in the dark. I heard a strange knock from my downstairs and hushed voices. As I climbed down my ladder, I heard the sound of footsteps climbing up my creaky wood stairs. I pause at my door way, which is to the left of the stairs, with the door remaining closed. I heard the steps approach my room, and then turn away and head for my parents room, which is just to the right of my room. Time passes as I silently stand in the doorway, and eventually everything is quite, as if no one had been in my house. I creeped out of my room and into the hallway, checking all the rooms on my top floor. It's still pitch black, but everything looks normal. Keep in mind, I have NO idea I am asleep. I completely thought this was real. I turned around and started for my room, when I hear a slight creak and an insidious noise that can only be described as a cry of despair coming from somewhere behind me. I'm still not sure why, but dream me ignored this, shut the door to my room, and crawls back into bed.
Thoroughly creeped out, dream me began to relax when I hear the scream again and a loud crash. All of a sudden, I heard footsteps running down the hall towards my room. THUMP THUMP THUMP.
And then I wake up with a start as my door crashes open and my trashcan falls over.
I still have NO idea how my door got pushed open and my trashcan knocked over, I think it was my dog, but damn it scared me more than anything when I awoke from a dream I thought was a reality to my door being pushed open. It was fucking scary.
TL;DR: I had a dream about a murderer in my house and my bedroom's door mysteriously opened at the same time it would have in the dream.
