Do you believe in ghosts? Psycho Clan, led by creator/director Timothy Haskell, conducted an online poll about people's paranormal experiences in order to gather material for its annual haunted house. They received thousands of responses, some of which come to life in Nightmare: Ghost Stories, currently being presented at CSV Cultural Center on Suffolk Street. TheaterMania recently stopped by to take a sneak peek at the ghoulish goings-on and talk with Haskell about his vision.
