Here's the weird dream of the century.
I usually dream that I am hanging out with my fav characters, like Gene and the Outlaw Star crew, Spike and the Bebop crew, Vash and friends, or even as a half-demon hanging out with Inuyasha and crew.
In this particular dream, I was with the Bebop crew, chasing down a bounty head. When get to his little hideout, we get ambushed by a bunch of his friends. We get into a huge gunfight. As I get up to take out one of the bounty head's friends, I get shot in my right shoulder. I switch the gun to my left hand and shot the f^*(er. After the fight, the guys take me to their "doctor". As he was pulling out the bullet from my shoulder, I woke up. I look around the room, saying to myself that that was one crazy dream. I look at my shoulder where I got shot in my dream, and I saw a blood stain on my shirt. That stain is still there, after several washes and three months.
Guess this proves that what the mind percieves as real, the body will too.
