Any piece of fiction that includes a ghost, or simply takes as a premise the possibility of ghosts or characters' belief in them. The "ghost" may appear of its own accord or be summoned by magic. Linked to the ghost is the idea of "hauntings", where a supernatural entity is tied to a place, object, or person.
Emphasises the horror of the unknowable and incomprehensible. Named after American author H. P. Lovecraft, whose work contained themes of cosmic dread, forbidden and dangerous knowledge, madness, non-human influences on humanity, religion and superstition, fate and inevitability, and the risks associated with scientific discoveries.
Books about or involving shapeshifters: those with the ability to physically transform through an inherently superhuman ability, divine intervention, demonic manipulation, sorcery, spells, or having inherited the ability.
A movement within horror fiction originating in the 1980s, distinguished by its graphic, often gory, depiction of violence, countercultural alignment and "hyperintensive horror with no limits." Regarded as a revolt against the "traditional, meekly suggestive horror story".
Books about or involving werewolves: humans with the ability to shapeshift into wolves (or therianthropic hybrid wolflike creatures) either purposely or after being placed under a curse or affliction (often a bite or scratch from another werewolf) with the transformations occurring on the night of a full moon.
