Sleep

from dali-gallery.com:
Sleep was painted for Edward James, a British millionaire who was Dalí’s patron from 1936 to 1939. Sleep deals with a subject that fascinated the Surrealists: the world of dreams. They believed that the freedom of the subconscious within sleep could be tapped into and then used creatively.
Sleep is a visual rendering of the body’s collapse into sleep, as if into a separate state of being. Against a deep blue summer sky, a huge disembodied head with eyes dissolved in sleep, hangs suspended over an almost empty landscape. The head is “soft,” appearing both vulnerable and distorted; what should be a neck tapers away to drop limply over a crutch. A dog appears, its head in a crutch, as if half asleep itself.
The head is propped above the land by a series of wooden crutches. The mouth, nose and also the eyes are all held in place by the crutches, suggesting that the head might disintegrate if they were removed. Crutches were a familiar sight in Dalí’s work.
