In this story by Julio Cortázar, a man hospitalized after a motorcycle accident drifts in and out between the “present” and a “dream” in which he is a member of an ancient tribe being hunted by Aztec warriors for sacrifice. As he struggles to stay awake in his hospital ward, his dream-self is captured, imprisoned, and carried up the temple steps for execution. At the moment of death, he recalls a dream about riding through an astonishing city on an enormous metal insect that whirred away between his legs. Themes include time and space (parallel worlds), existence, dreams vs. reality.
