There is a game all children try at some time or another. You fling out your arms and spin round and round, watching as the world blurs. First you are disoriented, but if you continue to spin long enough the world resolves itself, and you are no longer dizzy as you spin with the world blurring around you. Then you stop and the world lurches into regular shape. The dizziness strikes you like a thunderclap, everything lurches, moves. The world tilts around you.
