As an atheist I have a hard time scientifically believing in ghosts; with there be no hard evidence. However, I have had a lot of experiences in my life. Things that several people saw or heard as well. I work in a hospital and we have a room that is, for lack of a better word, haunted. Also, I played with a quija board a lot as a teenager and I believe that we brought some very evil things into my house. Crazy stuff was happening.
