An estimated 50 to 100 pilgrims to the Holy Land each year are afflicted by what psychiatrists call the Jerusalem syndrome. Most of them are evangelical Christians. One woman was convinced she was Jesus' mother, searching for her baby in Bethlehem. Another man was convinced he was King David. In some cases, people come to think of themselves as the Messiah. "There's a joke in psychiatry: if you talk to God, it's called praying; if God talks to you, you're nuts. In Jerusalem God seems to be particularly chatty around Easter, Passover and Christmas--the peak seasons for the syndrome," writes Chris Nashawaty in Wired magazine (March). The best cure is to leave the Holy Land.
