The haunted house where "they can do anything to you" is likely referring to McKamey Manor, an infamous extreme haunted house attraction in Tennessee. McKamey Manor is known for its survival horror-style events where participants are subjected to intense psychological and physical challenges, including abuse, humiliation, and simulated torture. Visitors must sign a detailed 40-page waiver and meet strict health and background requirements before entering. Some have reported being buried alive, waterboarded, and physically assaulted. The experience can last up to 8 to 36 hours, and no one has completed the full ordeal to claim the $20,000 prize offered. The haunt does not end until the owner, Russ McKamey, decides, and guests can only quit if allowed, sometimes after calling a safe word. The attraction has faced significant controversy and legal issues, with allegations of abuse and mistreatment of participants.
