From the artist's life
The Nightmare, with its demon crouched on a sleeping woman, so haunted audiences that Fuseli painted several versions; a print of it reportedly hung in Freud's apartment.

Henry Fuseli (1741–1825) was a Swiss-born Romantic painter who specialised in the dark, the dreamlike and the supernatural. His nightmarish The Nightmare became a sensation and an emblem of the irrational.
Fuseli's obsession with dream and terror anticipated Symbolism, Surrealism and the modern fascination with the unconscious.
