Ghost Hunters (2004)

Season 1: Episode 6

This investigation focuses on some friends of Brian's whose home is a deconsecrated 19th century church. They claim to have seen apparitions and to have heard strange noises. Also, one of the doors in the house opens by itself. The investigation turns up only orbs caused by dust. Jason determines that the sounds and orbs are caused by the settling of the wood beams when the church bell rings. The team is able to duplicate the opening door, giving a mundane explanation. No evidence of a haunting is found.
