The one I remember was this dream where I seem to be a detective or something. I was even wearing those typical detective outfits you see in movies (hat, long coat, tie)... and the setting was sort of noir-esque...lol... I remember following a suspicious man in a castle or a corridor and he went into a room in a closet?? And then there was a woman there who kept telling me to kill something...I dunno, maybe some sort of entity or creature inside the closet and I just kept reassuring her. So I killed it for her, although I don't remember how exactly. Then the scene suddenly jumps where I find myself sitting in a car waiting for something, then all of a sudden another man jumps from the highest point of a building and lands on top of the hood of the car, dead, and I just stare, dumbfounded. It was all very nonsensical. Also, in the dream, I was the opposite sex for some reason.
I've had weirder dreams, but that's the one I always remember. Probably 'cause it was so dark and kinda scary (to me).
