Pictures of ghosts (demons, devils, negative energies, etc.) by Type

This is a picture of the sorcerer, a higher ghost possessing Dr. Datta. He was the root cause behind the symptoms displayed by Dr. Datta. The symptoms included heaviness of body, slowing of movements, intellectual blunting, difficulty in speaking etc. An interesting fact is that during childhood, Dr. Datta used to get frequent nightmares of a snake chasing him. He would wake up drenched in sweat and there would be frequent bedwetting.
