I also read in a couple days, PROOF OF LIFE AFTER LIFE, by Raymond Moody, Ph.d & M.D. 
Moody coined the term "Near Death Experience" in his first book, LIFE AFTER LIFE, 1975, & changed the world. He also talks in both books about the mirror, "Psychomanteum," through which people can communicate with "dead" relatives & friends. Moody learned about this method from the ancient Greeks, who used it with extreme success. It's been verified even in TV shows like OPRAH.
