From century to century manifestations of supernatural forces reveal a surprising similarity. Ancient Greeks immortalized stories about ghosts, Romans — about haunted houses. There is no culture where there is no tradition of communication between the living and the dead. The American philosopher WILLIAM James wrote in 1897: "Extraordinary phenomena undoubtedly exist. On any page of history you will find descriptions of prophecies, predictions, possession of the devil, visions, trance, divination, ecstasy, miraculous healing and, on the contrary, the evil eye and damage.
But over time attitude to such phenomena has changed. Now that we hear about the poltergeist, we don't tend to deny it, we just know how to treat it as it falls out of a number of normal phenomena. Blindly believe in the existence of "restless ghosts" we can not, because there is no direct evidence. At the same time, it would be wrong to deny reality, claiming that it is only a game of imagination. Among some scientists, there is growing confidence that the phenomenon of poltergeist is a hitherto unknown energy of the human brain.
And blind faith in supernatural phenomena, and their complete denial only lead us away from the truth. The surest way to understand this is to treat every fact of this kind as something real.
All the phenomena and events described in the pages of this book were initially perceived as something supernatural. Sometimes they quickly received explanation, quite often any of them unfolded over time, but many and to this day remain puzzles. Man's interpretation of the mysterious movements of his own soul speaks more of the nature of the soul than of nature itself. And this is natural: after all, the inner world of man is still unknown, as much around us.
