Yeah, I know exactly what you are thinking. I didn't believe in ghosts either, but I got a hit on my security camera I couldn't explain. So I put in more cameras and things kept popping up and in multiple places and forms. I don't know exactly how to explain it so the pictures and videos can speak for themselves. They show up in Infra-red mode only I can't see them with my eyes, and nothing on the cameras, unless it is in IR mode.
