This painting marks the culmination of Nash’s personal response to Surrealism, of which he had been aware since the late 1920s. As the title suggests, it echoes the Surrealists’ fascination with Freud’s theories of the power of dreams to reveal the unconscious. Nash explained that various elements were symbolic: the self-regarding hawk belongs to the material world, while the spheres reflected in the mirror refer to the soul. Typically, Nash set this scene on the coast of Dorset, unearthing the uncanny within the English landscape.
