On the surface, curling up with an Agatha Christie novel may seem to have little in common with screaming one's lungs out in a haunted mansion. But Scrivner says that people simply choose the kind of scary play that is right for them, where the fear feels exciting, but not upsetting. For some, reading a crime story may be enough to create a realistic scenario in their minds, while others may need the stimulation of a physically immersive setting: "There's this sweet spot of fear, where you want to toe the line between reality and fiction, where it seems to be the most fun".
