Supernatural horror film is a film genre that combines aspects of supernatural film and horror film. Supernatural occurrences in such films often include ghosts and demons, and many supernatural horror films have elements of religion. Common themes in the genre are the afterlife, the Devil, and demonic possession. Not all supernatural horror films focus on religion, and they can have "more vivid and gruesome violence".
