Interesting.
Just searched "ghost" and found this thread. So much controversy on the subject in mainstream christianity. I never understood that. I can understand taboos associated with it, it does seem to be a perilous ground to tread on.
I know my dear old Catholic Grandma played with ouija board for a while, and later tarot. Seems she was intrigued by ghosts. Of course, she gave up ouija after it scared her, though she never dislosed why. Years later, trying tarot, she had a similar experience, and never touched them again either.
