Nightmares Fear Factory

The Nightmares Fear Factory is a psychological haunted house attraction in Niagara Falls, Ontario, Canada. They are known for posting images of their visitors just as they have been shocked to a Flickr account.
The attraction is allegedly built in an old coffin factory. The former owner of the factory, Abraham Mortimer, was killed when a stack of coffins collapsed upon him.
Patrons are told that if they get too scared they can say the safety-word "nightmares" and they will escort you out. However, sometimes they will not escort you out and continue the scaring even worse than before. In the last five years, about a half-million people have gone through, and many have opted out part-way and had their names added to a public "chicken list". Over 161,000 people, (as of 2019), have had to leave through the chicken exit.
The tour takes about 10 minutes and is in total darkness, except for small red lights on the floors, walls and ceiling that patrons must follow in order to get through the haunted house.
Unlike conventional haunted houses, the Nightmares Fear Factory doesn't rely primarily on blood and gore in order to induce fear. Rather, there are live actors in scary costumes that come at the patrons out of the darkness and taunt them, yell at them, speak in creepy voices, etc. They have been known to grab, push and pull patrons in order to get a reaction. There are also scary sounds like growls, eerie music, spooky voices, yelling, and so on.
Highlights of the attraction include a room where the walls appear to shrink, a shaky drawbridge, a car charging at the tourists, and a room where two black air mattresses inflate on the tourists and they are forced to crawl on the ground and push the mattresses out of the way in order to survive claustrophobia.
