swing back and forth("The place was very haunted and very creepy... we experienced a lot of things there," Mark said. He recalled one night they were walking the halls and chatting about exorcisms when they heard a loud crashing sound. They discovered a heavy piece of conduit hanging from the ceiling "angrily and violently just swinging back and forth." Mark believes their conversation, which mentioned the name Jesus, may have disturbed some entity in the building.coasttocoastam.comART Vancouver)
