This is a great website if you want to learn how to handle a "problem ghost." It's a page from a larger, highly intriguing site called Hollow Hill. You can find all sorts of information there, from Ghost Hunting to real photographs of ghosts.
Now, I don't know if I believe in ghosts, but I know that I believe in the possibility of ghosts. I've met (and loved) to many sane, intelligent people who have related contact with departed loved ones and/or seen the unexplainable to call it all hogwash.
Either way, this is a wonderful site for helping me with my Extreme Haunting series and I hope that you'll find it as interesting as I did!
