The Jerusalem Syndrome: Why Some Religious Tourists Believe They Are the Messiah | Wired Magazine | Wired.com:
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. It affects an estimated 50 to 100 tourists each year, the overwhelming majority of whom are evangelical Christians. Some of these cases simply involve tourists becoming momentarily overwhelmed by the religious history of the Holy City, finding themselves discombobulated after an afternoon at the Wailing Wall or experiencing a tsunami of obsessive thoughts after walking the Stations of the Cross. But more severe cases can lead otherwise normal housewives from Dallas or healthy tool-and-die manufacturers from Toledo to hear the voices of angels or fashion the bedsheets of their hotel rooms into makeshift togas and disappear into the Old City babbling prophecy.
