Yes, I believe there are good an bad ghost. I worked in Skilled Nursing Home and beleive me there were some strange things that went on. When I first started there co workers talked about the black thing, of course I didn't believe . About 1 year latter I could fill something falling me . So when I turned around there it was. Looked like a puff of black smoke. Well I could go on about the things that happened. Maybe another time.
