These are the oddly hilarious faces of spooked visitors at the Nightmares Fear Factory in Niagara Falls, Ontario, Canada. The house is said to stand on the site of a former coffin factory where, legend has it, the owner was killed when a stack of caskets fell on him. Visitors are photographed at the moment they spot what seems to be a car full of ghosts about to run them over. The attraction is said to be so frightening that visitors have a safety word – 'nightmares' – which they can utter at any time to be escorted out
