I once had this dream as a teen that I was in this abandoned house in this huge open field (think of the house in Courage the Cowardly Dog). Well, I enter the house and time just felt like it stopped. I explore the house for a bit, with warm yet cold light coming in through the windows, reflecting off every dust particle in the air.
As I finish exploring the bottom floor I head up the stairs and all of the sudden I get a feeling like something is chasing me. My adrenaline rushes and I run as fast as I can. The hallways keep turning, left, right, left and then right again, until I come to a dead end and look above me to see the entrance to the attic. I thought it was the perfect place to run for some reason.. well anyways, once in the attic I find some old furniture and throw it towards the entrance in an attempt to block the way of whatever it was that was chasing me.
Once I felt that it was secured, I noticed the only piece of furniture that wasn't a part of my barricade was a mirror. It was one of those tall, oval mirrors. I approached it slowly, feeling that it was a bad idea. Slowly I inch my way in front of the mirror, expecting something bad to happen. It took forever but I can finally see my entire body. And as I stare in to it I feel my persuer once again, as if he's right behind me but I see nothing. As I strain my eyes to find him, I feel a hand grab my shoulder and I swing around in an attempt to punch whatever it was.
As I punched I woke up to my fist flying through the air and just missing my mothers face by a few inches. I panicked and was so out of it and didn't understand at all. My mother calms me down and apparently was just waking me up to get ready for school.
tl;dr: I was being chased by a vampire and when I tried to punch it I woke up and was trying to punch my mother.
Probably the weirdest, most real dream i've ever had.
