I saw my first ghost when i was about 10. Standing over me in bed. I saw another when I was a soldier in the barracks in Greece a few years back, I think it was the ghost of an old German soldier who got killed many years ago in WW2.
I don't believe in any of that. I think that people can create an atmosphere for other people that makes their imaginations run wild and they then convince themselves that certain things are happening that actually aren't. That is what happens on those stupid reality tv ghost shows. As a watcher, I can see how cheesy and stupid it is. As the people in the show, they are getting freaked out and scaring each other into thinking that is something more than it actually is. I did an experiment once and made up some ghost story. I told it to my friends (this was when I was a teenager) I made it very convincing. Told them things that had happened to me. I was not surprised that their imaginations took over and they all of a sudden started seeing ghosts in my house and freaked themselves out so much they had to leave. To this day they swear my house is haunted.
