Ghosts are at the top of our paranormal interest list because they are evidence about the greatest question of all: What happens to us after we die? Religions all claim to know the answer, but human experience does not fit neatly into religious boxes. Science has tried to find the answer, but again, human experience, and the phenomena themselves, do not fi t neatly into the science box either. Unable to supply ironclad answers, both camps tell us to ignore the phenomena: it’s illusion, delusion, all in our heads, demonic, tricks of light and sight, brain chemical reactions, and so forth.
