Why your worst nightmares about watching horror movies are unfounded

Films about chainsaw killers, demonic possession, and ghostly intruders make some of us scream with joy. But while horror fans are attracted to movies designed to scare us, others shudder already at the thought of the sweat-drenched nightmares that terrifying movies often trigger. The fear of sleepless nights and the widespread beliefs that horror movies can have negative psychological effects and display immorality make some of us very, very nervous about them. But should we be concerned?

In this book, horror-expert Mathias Clasen delves into the psychological science of horror cinema to bust some of the worst myths and correct the biggest misunderstandings surrounding the genre. In short and highly readable chapters peppered with vivid anecdotes and examples, he addresses the nervous person's most pressing questions: What are the effects of horror films on our mental and physical health? Why do they often cause nightmares? Aren't horror movies immoral and a bad influence on children and adolescents? Shouldn't we be concerned about what the current popularity of horror movies says about society and its values? While media psychologists have demonstrated that horror films indeed have the potential to harm us, Clasen reveals that the scientific evidence also contains a second story that is often overlooked: horror movies can also help us confront and manage fear and often foster prosocial values.
