Horror intends to create an eerie and frightening atmosphere for the reader. Prevalent elements include ghosts, demons, vampires, werewolves, ghouls, the Devil, witches, monsters, dystopian and apocalyptic worlds, serial killers, cannibalism, psychopaths, cults, dark magic, Satanism, the macabre, gore, and torture.“The oldest and strongest emotion of mankind is fear, and the oldest and strongest kind of fear is fear of the unknown. These facts few psychologists will dispute, and their admitted truth must establish for all time the genuineness and dignity of the weirdly horrible tale as a literary form…As may naturally be expected of a form so closely connected with primal emotion, the horror-tale is as old as human thought and speech themselves”.
