I always thought so. I've seen ghosts at where I work. It's kinda creepy...I've also had dreams in which I was commanded to kill...those are the weirdest dreams on earth. Also, something fucked up was a song that came to me...something called the killing day...was like...2 nights ago
One time I dreamed I was walking in some sort of undrground hall, and suddenly this women started screaming to me that I should escape with her. But then my old gym teacher was comming up to me trying to stop me. I got a knife and slith his troath, which was weird because he was always a pretty cool guy. That was the first time I've ever killed someone in my dreams and saw it with so much detail, it made me feel pretty weird when I woke up...
