On August 6, 1978, Pope Paul VI died at 9:40AM, Roman time. At that very moment, his Polish alarm clock, purchased in Warsaw in 1924, went off.
Mary Roach, who takes a naturalistic view of such phenomena, needless to say offers little light on such subjects in her book, Spook: Science Tackles the Afterlife (WW. Norton, 2006). But you can find a good review of the book by Arthur C.
Sippo in the May issue of New Oxford Review.
