I read a book around 15 years ago. The author interviewed many instances of abductions. He began to notice that some of the stories of a few of them were exactly the same, and asked for the abductees to meet in person. When they met, they realized that they knew each other. They had been abducted together, multiple times, since childhood. They lived on opposites sides of the country and had never met in person, but knew each other! One of these abductees was a political figure who asked to remain anonymous for fear of ridicule.
