When this work was first published in 1970, it shredded the then-trendy nuts-and-bolts extraterrestrial hypothesis for UFOs in favor of one that linked UFOs to a variety of paranormal and supernatural phenomena that have taken place throughout history. Keel was one of the first to note that the UFO phenomenon appears in different disguises - and that one could not begin to decipher this great mystery without first taking into account its many and varied deliberate deceptions.

Is there a single intelligent force behind all religious, occult, and UFO phenomena? Strange manifestations have haunted humans since prehistoric times. Beams of light, voices from the heavens, the "little people", gods and devils, ghosts and monsters, and UFOs have all had a prominent place in our history and legends. In this dark work, John Keel explores these phenomena, and in doing so reveals the shocking truth about our present position and future destiny in the cosmic scheme of things.

In Dimensions, Dr. Jacques Vallee reexamines the historical record that led to the modern UFO phenomenon and to the belief in alien contact. He then tackles the enigma of abduction reports, which come from various times and various countries, as well as the psychic and spiritual components of the contact experience. In the last portion of the book, he notes the factors that inhibit research into the phenomenon - the triple coverup and political motivations - and concludes that the extraterrestrial theory is simply not strange enough to explain the facts.

Flying Saucer to the Center of Your Mind is a collection of magazine articles and lectures by the man many consider to be not only the 20th century’s premiere investigator of all things unusual and “Fortean,” but also our very own 20th-century “Mark Twain”: John A. Keel. Many of the articles in this anthology and its companion volumes, "The Outer Limits of the Twilight Zone" and "Searching for the String," were revolutionary, and explored ideas popularized in Keel’s classic books.

During 1966 and 1967, when he was subject to nonstop surveillance and harassment from both human and supernatural spooks, intrepid Fortean investigator John A. Keel made extensive field notes concerning the phenomena he was confronting in West Virginia and New York: UFOs, Men in Black, creature entities, ultraterrestrials, and odd coincidences and synchronicities. The result was a series of concise, thematically related reports, many of which were incorporated into magazine articles for Saga, Fate, and Flying Saucer Review.
