Virginia Tighe Morrow, 72, whose revelation under hypnosis of a past life as a 19th century Irishwoman sparked a 1950s debate over reincarnation and served as the basis for the book and subsequent movie titled "The Search for Bridey Murphy," died July 12 in her suburban Denver home, family members said Thursday. She was married to automobile dealer Hugh Tighe when she met the book's author, Morey Bernstein, at a party. Mr. Bernstein, a local businessman interested in hypnosis and reincarnation, offered to hypnotize her to relieve her allergies. In a half-dozen hypnosis sessions, she related a detailed story of her life as Bridey Murphy in Ireland, recounting events in a thick Irish brogue completely unlike her normal speech. A national controversy over reincarnation arose after Mr. Bernstein revealed her story, especially after he decided in 1954 to spell it all out in a book. Although she complained that news media and the curious public interrupted her family life, she turned down lucrative offers to state in magazine articles that the experience had ruined her life.
