Lovecraftian Horror

Lovecraftian horror is a subgenre of horror fiction that emphasizes the cosmic horror of the unknown (or unknowable) more than gore or other elements of shock. Cosmic horror frequently presents a dark and nihilistic universe, where humanity is preyed upon as a mere plaything for all kinds of inconceivable horrors, and all our ideals are naught but cruel illusions

It is named after and takes inspiration from the works of American author H. P. Lovecraft (1890–1937), who was wont to portray a naturalistic fusion of horror and science fiction in which presumptions about the nature of reality are "eroded", but does not need to relate to his actual writings.
