I Believe In Ghosts

Do you? When I say that I believe in ghosts, I'm not necessarily referring to the spirits of those who have died. I don't know what they are, and I guess that's why I'm so fascinated with it. They could be spirits of those who have passed, or they could be something entirely different. I'm interested in your thoughts. I can't disregard my experiences over the years. My curiosity won't let me.
