Fuck, I had this really freaky-shit dream...
There was a huge empty theater... it was ruined... and some spelunkers (thats what I think they were) dropped through the roof, came down on a line and started to explore the theater. All of a sudden there was this loud shriek, and this thing, which looked like a rotting human carcass with flames coming out of its eye sockets comes running down towards the stage, where the spelunkers were. It had a blade like a knife, but with another knife coming out of the side of the blade at a 90 degree angle. It ran at the spelunkers, who were terrifyed, and killed them all; decapitating some and mutilating others. I had a great 3rd person view to all of this gore
and then I woke up...
I was so scared, I stayed up the whole night.
That was the worst nightmare I ever had.
