Bilocation is the appearance of an individual in two places simultaneously. What exactly occurs in the phenomenon of bilocation is uncertain. The prevailing theory suggests that it is a projection of a double. In appearance to others the double may appear to be a solid physical form, or may be ghostly. Usually this double acts strangely and mechanically and does not acknowledge others when spoken to.
Although it is uncommon, bilocation is an ancient phenomenon. It is claimed to have been experienced, and even practiced by will, by mystics, ecstatics, saints, monks, holy persons, and magical adepts. Several Christian saints and monks were adept at bilocation such as St. Anthony of Padua, St. Ambrose of Milan, St. Severus of Ravenna, and Padre Pio of Italy. In 1774, St. Alphonsus Maria de’Ligouri was seen at the bedside of the dying Pope Clement XIV, when in fact the saint was confined to his cell in a location that was a four-day journey away.
A pioneer psychical researcher, Frederic W. H. Myers, one of the founders of the Society for Psychical Research in England, along with others collected and studied reports of bilocation, however the phenomenon has received little interest in modern times.
Spontaneous and involuntary bilocation sometimes presages or heralds the death of the individual seen.
