I mean to post this earlier in response to what a ghost is. I have always been torn as to exactly what a ghost is. Being a Christian I know what is supposed to happen when we die, yet I also know that ghosts were mentioned in the Bible. I dont know if I will ever understand fully what a ghost really is but I do know there is a lot that we are unsure of in this world. Lots of stuff we cannot explain. I dont believe all of that is demon related by any means. Some stuff we likely create on our own. The danger is letting the search for the unexplained lead you into dark things like witchcraft or Ouija boards and stuff like that. I do go into investigations with a prayer for protection before starting just in case there is something there that may want to hurt me, thus the demonic aspect. I have been fortunate to have not experienced anything at that level but I am not nieve enough to think it does not exist. Anyway, at least you know how I feel about it.
