Ah, just want you want when you're walking round a haunted house: some joker taking a snap of you then sticking it on the internet.
Visitors to the Nightmare Fears Factory in Niagara Falls, Canada, are obliged to navigate their way round the supposedly haunted building in total darkness while live actors jump out of them. What japes! (Well, it's not like there's anything else to do in Niagara Falls, is it? Who wants to look at a load of boring old water falling over a load of boring old rocks?)
Anyway, it turns out the Nightmare Fears Factory team have been using hidden cameras to take pictures of their guests' terrified reactions, which they've then posted on the company's Facebook page.
And it turns out they're all pretty funny. But don't just take our word for it. Browse our gallery and see for yourselves...
