Found footage horror uses recovered recordings, damaged tapes, surveillance footage, livestreams, and fragmented evidence to create fear through realism and uncertainty. From The Blair Witch Project and REC to Paranormal Activity and Lake Mungo, the genre builds terror through incomplete recordings, hidden details, corrupted media, and the terrifying sense that horrifying events were captured accidentally. These 70 Found Footage Horror Writing Prompts explore abandoned recordings, emergency broadcasts, paranormal investigations, missing expeditions, surveillance horror, analog terror, and fragmented storytelling through plot hooks, title ideas, opening lines, setting prompts, character concepts, and cinematic visual inspiration.
