The wolf man’s dream draws a clear reference to the cave paintings, the perception of movement, the surface-like quality of figures, and the absence of depth. It is also influenced by the dream of Sergei Pankejeff: Pankejeff was lying in bed when the window swung open. Peering outside he saw six or seven white wolves sitting in the tree outside his bedroom, their eyes fixed on him. Terrified by their gaze, he woke up screaming. (A dream from psychoanalysis history)
