I have discovered a whole new world of podcasts on iHeart Radio. One is called "The Confessionals" and his guest was a guy named Danny who goes into abandoned vacant buildings to capture paranormal, spirits and ghosts on camera. This video is pretty convincing and the way he runs away screaming like a little girl tells me it must be real. The ghost sighting happens at the 2:05 mark of the video. Be prepared to go back and pause it so you get get a good look at the ghost nun. It is one of the creepiest videos I've seen to date.
