Written in 1967.
"He awoke and heard voices, but they seemed to come through an echo chamber and the words were garbled; he could not understand them. He was sick, and he shouted into the darkness, but he made no sound. He tried to extend his arms and seemed to fly, with nothing under his feet, soaring and swooping and dipping and diving. All at once he felt a lurching sensation and dropped gratefully into nothing at all."
