It's division of reality which supposedly occurred due to the operation of the linear accelerator at Montauk, during the Montauk Experiment. Also the details of what they were doing there, to where not just a few people had picked this up telepathically, but millions.
It was the only time that the hidden US establishment ever broadcasted highly detailed secret information, directly to the American public. While I don't know the exact details of how this occurred, I do know that it happened.
Check the two by two controlled wild animal parade and this was everything from rabbits to mountain lions walking up the main street of Montauk, much to the disbelief of the stunned people standing on the sidewalks.
The Montauk Experiment, was the best top secret ever publicly broadcasted. It's just that the details were so bizarre, so unbelievable, that people had a hard time as to what they were actually mentally receiving, had been the real truth.
