There was a similar horror experience to Room 13 somewhere else in England the other year. You had to sign a waiver, go in alone etc. It was called Psychomanteum.
A reporter went and said it was horrific, I don't think she gave full details but ended up using a safe word to get out.
Someone I know went and also said it was horrendous, I can't remember exactly what she said happened, but it was stuff like being water boarded, having your head put in a toilet, a bag put over your head, a man laying on top of you & blurting explicits at you. (You had to pay an extra fee on top of entrance for this experience in this room I must add!)
It was in the news as a rape charity condemned it, saying it was wrong to have this as entertainment.
