[LOOKAYANNER]

There should have been a choice titled, "Not Sure, I'll Need Some Kind Of Proof".

That's kind of where I fit. I've never seen or heard anything unusual that has made me believe in the supernatural. And I don't have much confidence in the shows on TV that investigate ghosts and hauntings. Harry Houdini proved many years ago, before TV and film tricks, that most people who say these things or act like they can contact the hereafter, were frauds and fakes.
I think most people who say they see or hear ghost actually believe that they did see or hear something, but in most cases there is an explanation. An optical/auditory illusion. And I think if you are predisposed to believe these things (example: growing up listening to grandma tell ghost storys she's experienced), then you are much more likely to have a ghost experience.
