Photos of terrified visitors to Canadian haunted house go viral

If you are looking for a real scare this Halloween season, head to Niagara Falls Canada.

Unfortunately for people caught on hidden cameras at Nightmares Fear Factory, the only thing that may be scarier than what they witness when caught on camera is seeing their pictures splashed all over the Internet.

"This is by far the scariest haunted house we have ever been in," says Larry Johnson in the comments section of the Nightmares website. "If you decide to enter make sure you leave a will with family members."

The owners of the haunted house have been posting the photos to Facebook for two years and Flicker for one, but they really began to get a lot of attention after being featured by Buzzfeed earlier in October. They were even featured on the Tonight Show with Jay Leno and have made their way to countries including Australia, England and Japan.
