Is it possible to feel fear in the theatre? Yes it is, if Jeremy Dyson’s and Andy Nyman’s evening of terror tales is anything to go by. It takes the form of a lecture delivered by paranormal expert Prof Goodman (Nyman) who relates stories of ghostly encounters experienced by others, and one that happened to him when he was a boy and called by his schoolmates “Jewy Goodman”. Despite the jibe, it was not he who was the victim there. Take a cushion, and I don’t mean to sit on.
