TAURUS (April 20-May 20): U.S. Confederate Gen. Richard S. Ewell (1817-'72) sometimes had episodes in which he truly thought he was a bird. Princess Alexandria of Bavaria (1826-'75) believed that when she was young, she'd eaten a glass piano. Then there was Prussian military officer Gebhard Leberecht von Blucher (1742-1819), who thought he was pregnant with an elephant. Sad, funny and crazy, right? Yet we all have fixed delusions. They're less bizarre than these, but they can still be debilitating. What are yours? Do you secretly believe a certain turning point in your past scarred you forever? Are you wracked with anger or guilt because of something that may not have actually happened the way you recall? Good news: Now's a great time to shed fixed delusions.
