"C. W. Shumway observed the Los Angeles revival of 1906 and noted six basic symptoms: complete loss of rational control; dominance of emotion that leads to hysteria; absence of thought or will; automatic functioning of the speech organs; amnesia; and occasional sporadic physical manifestations such as jerking or twitching. Eusebius observed similar phenomena around the year 300, saying that the false prophet begins by a deliberate suppression of conscious thought, and ends in a delirium over which he has no control."
