Demonic Foes: My Twenty-Five Years as a Psychiatrist Investigating Possessions, Diabolic Attacks, and the Paranormal

A world-famous psychiatrist speaks openly for the first time about his 25-year experience studying people obsessed by demons. The cases he documented—levitation, reading thoughts at a distance, controlling animals, remote viewing, and more—turned a skeptical scholar and staunch atheist into a truly believing person.

Dr. Gallaher’s book tells us: in this world there is room for “dark” demonic forces and paranormal phenomena, whose existence is currently accepted to be denied. An authoritative New York psychiatrist, Dr. Richard Gallaher, has an unusual profession. He is a specialist in demon possession… and a scientific consultant in exorcism. Many years ago, a priest knocked on his door and asked him to investigate a peculiar patient. After tests, Gallaher was surprised: the girl was mentally healthy, yet the demon demonstrated extrasensory abilities—revealing detailed information about the lives of strangers, including the psychiatrist’s mother. She could control pets’ behavior and spoke several languages fluently—only when she was in a trance. She called herself a priestess of a satanic cult in which she had been for many years. And after meeting her, frightening things began happening—to both the priest and the psychiatrist.

Now Dr. Gallaher is a world-renowned specialist who devoted his life to studying demonic possession. Exorcists of all faiths consult him to distinguish real possession from a mental or medical illness. Gallaher is absolutely certain: the true interference of demons is not psychosis, depression, schizophrenia, or an epileptic seizure—but something else entirely. His book tells us: in this world there is room for “dark” demonic forces that science cannot explain. And it is very dangerous to underestimate how much influence they have on people… “A thrilling, captivating look at the phenomenon of demonic possession, written by an expert in the field of psychiatry… Believers will be delighted, skeptics will enjoy the debate, and even the most skeptical readers will be surprised by the secrets of human behavior investigated in this book.” — Kirkus Review
