@hamilton,
I definately agree with you. I mean, anything is possible and I know that they are real too. People just always tell me that they don't exist and I can't see why not. They don't really give good reasons as to why they may not exist. May I ask you, have you had experiences with such things? A couple of my friends have and that's why I believe in them. I even had an experience of my own with ghosts.
