The narrator becomes an omnipotent being commanding cosmic forces and impossible worlds, only to find his godlike dream empire collapsing into a nightmare of pursuing monsters and existential dread. Smith's baroque, ornate style creates a vertigo-inducing journey through impossible geometries, alien worlds, and grotesque manifestations that culminates in a cosmic horror revelation.

What Was It?
Written by Fitz James O'Brien in the 19th century, "What Was It?" is a pioneering work of scientific horror that transforms the haunted house tale into an investigation of the impossible.
