“A number of revelators and UFO contactees have since mentioned to me that just before the appearance of an entity they were aware of a strange buzzing sound. Witnesses of unexplained aerial phenomenon have also referred to a buzzing or rushing sound shortly before the 'flying saucer' appeared over them. I am also reminded that great deal of poltergeist activity produces a preparatory 'signal' of a buzzing, rasping, or winding noise.”
