Ghosts and Demons

Question from Bob on 10/15/2007:

Dr.,

I was watching "Ghost Hunters" again and someone got knocked over by something invisible and it was caught on camera.

Now, I am sure the guy could have lost his balance. But, hypothetically speaking, can ghosts (damned souls, demons) hurt people physically? Isn't that called Demonic Obsession?

Thanks for your time.

Dear Bob,

Yes, demons can hurt people physically. It is hard, however, to judge any particular incident.
