"[Geza] Roheim said that animals in dreams are ancestral beings. The landscapes in which they live are the introjected terrain of our genital anatomy. It is a world fashioned from our own interior. The dream is a tactile regression, emitting visual phantoms for the inner eye, which has been deprived of its contact with the outer world. The dream state reverses that progressive, oral, eye-dominated thrust of the conscious mind. Sleep is a reverse transformation, a shift toward the beginning, toward ancestors. That is why, he says, dreams are related to initiation and to totemism."
—Shepard, “Thinking Animals”
