The Huffington Post has a fascinating article written by Dan Aykroyd. Here pretty soon Dan will be traveling with his father to promote his book A History of Ghosts. Below is a blurb from the article:

Hard-line skeptics such as my writing partner on Ghostbusters, Harold Ramis, believe that the invisible world can not reasonably encompass these lingering presences, their occasional appearances to us and their subsequent actions. However it is reported that General George Patton who fervently believed that he was a Roman Legionary in a previous life, appeared to one of his sisters in New York at the exact moment he died in an American military hospital in Germany. She described him as sitting casually inside her apartment window sill in full uniform. His other sister said that the General telephoned her in Boston as well to say good-bye at the time of his passing.
