Awhile back I got into a debate with someone else in the field about the limits of a human ghost. Some people follow the school of thought that, a human ghost can only do so much, and that certain kinds of extreme activity can only be the work of a demon. Well over the years I have not seen a demon, but I have dealt with many human ghosts and some of the activity they can pull off is quite impressive.When a ghost teams up with other ghosts or some other entity that increases their ability to perform some amazing feats. Then there are occasions where IMPS take up with human spirits. IMPS are basically groupies that take up with a ghost and join in the agenda for chaos and mischief.
