McKamey Manor is a haunted house so scary, so intense and disturbing that no one has ever been able to make it all the way to the end. In fact, they'll give you $20,000 if you can. Sounds fun right?

Now, we're not talking about any normal haunted house experience. The McKamey Manor in Summertown, Tennessee has been dubbed "The World's Scariest Haunted House" for seemingly good reasons. With this haunted house, there are quite a few requirements before you can even start.

1. You must be at least 21-years-old.
2. Complete a sports physical.
3. Pass a drug test.
4. Provide proof of medical insurance.
5. Be screened by phone.
6. Read and sign a forty-page waiver.

I'm not sure if any of these are actually really needed or if it's just a psychological freak-out move to make you give up.

Oh, there's more...

From khak.com -

"The visitors must then watch a 2-hour video called 'And Then There Were None', which features footage of every visitor from July 2017 and August 2019 quitting before the end of the experience. Visitors leave by uttering the code phrase, 'You really don't want to do this.'"

That's right, there is a safeword. My heart is starting to race just thinking about it.

You see, part of what makes this haunted house so unbearable is that it changes for each person based on their own personal fears.

You could just not tell them the truth about what your real fears are right? Wrong. Another part of the process is hypnosis, and that's apparently how they'll get all of the info you don't want them to know.

It can also take up to 10 hours to complete!

If you're thinking about giving this a shot, you might change your mind after watching the 2019 trailer below.
