I know this is old news and sorry for that. However I do have something to add to this discussion.
BLACKOUT
The BLACKOUT experience is said to be a horror based experience, but imho it's more of a psychological torture. People pay big money to participate, and are assaulted, bound , abused, and frightened to near death, all because they chose to do so.
I would absolutely love to sign up for a BLACKOUT or similar deal.
