In 1981, I was a reporter for the New York Daily News, when I investigated three haunted houses. The most compelling case came from Dr. Karlis Osis, a well-known researcher who frequently takes on assignments from the CIA and other top-secret organizations. Osis would later help me in an article about out-of-body research, of which he is considered the world authority. Although I was skeptical of the first two cases I investigated, I found the case of Jean and Patti to be difficult to disbelieve. Whether spirits are emanations of our own minds, or energies from another dimension is the million-dollar question. Someday, I hope we discover the answer.
