I have just recently started reading “The source field investigations” by David Wilcock and I was astounded to read about the life-long studies and experiments of Cleve Backster.
While he was still a student at Rutgers University he became fascinated with a hypnosis technique learned from a teacher, which he successfully tested on his roommate. He was able to hypnotize him and make him go downstairs, ask permission to keep the lights on until late, sign the register and come back into the room.
“When Backster brought his roommate back out of hypnosis, he didn’t even realize anything had happened to him: ‘See? It doesn’t work. This so-called hypnosis is a bunch of baloney.’
When they walked down to the on-duty professor, he confirmed that Backster’s roommate had just come and asked permission a few minutes earlier — but the roommate couldn’t believe it was real. He was then shocked to discover his own signature in the late lights log.” 
|Prof. Cleve Backster|
Backster began researching hypnosis — reading as many books as he could find on the subject, which were not that many in the late 1930s — and performed additional successful experiments. After the devastating attack on Pearl Harbor in 1941, Backster joined the military ROTC program at Texas A & M University — and there he began making frequent demonstrations of hypnosis to larger audiences. (…)
One man was told he would not be able to see Backster in the room for the next thirty minutes after he woke up. Indeed, once this subject was brought out of hypnosis, he could not see Backster at all. Just to test how far this would go, Backster picked up a cigarette and blew out some smoke, although he was not a smoker.
This man saw the cigarette and the smoke levitating in the air, but he could not see anyone holding it—and he became very alarmed. (…)
After his university training, Cleve Backster eventually joined the U.S. Counter-Intelligence Corps, and lectured on the potential danger of foreign powers using hypnosis to extract classified information from overseas government personnel. Backster took a huge risk to demonstrate the seriousness of this subject to a high-ranking military officer.
With her permission, Backster hypnotized the secretary of the commanding general of the Counter-Intelligence Corps. While under hypnosis, he asked her to remove a highly classified document from the general’s locked file cabinet—and she willingly obeyed. Backster told her she would not remember what she had done when she awoke — and sure enough, she had no idea she had just leaked very sensitive information when he brought her back.” 
Cleve Backster: “That night I secured the document in my locked file and the next day presented it to the General. I explained to him that I might be risking a court martial, but hoped instead to expedite further consideration of the importance of my research. Rather than a court martial, on December 17, 1947, I received a very favorable letter of recommendation from the General, stating that my research was ‘of high importance to military intelligence.’ Then positive things started to happen.” 
From April 27, 1948, Backster started working for the CIA and studied with Leonarde Keeler — a pioneer in the use of the polygraph. He left the Agency in 1951, soon after Keeler’s death and worked as the director of “Keeler Polygraphy Institute” in Chicago. From 1958, Backster begun intensive polygraph research and after having the brilliant idea of connecting one of his plants to the polygraph, and changed the history of science forever.
“Much to his surprise, the plant did not have a smooth, flat pattern of electrical activity—it was surprisingly jagged and alive, changing moment to moment. Then, as Backster kept watching in amazement, it got a whole lot more interesting.
‘About one minute into the chart recording, the tracing exhibited a short-term change in contour — similar to a reaction pattern typical of a human subject who might have been briefly experiencing the fear of detection. (…)
Then, after about fourteen minutes of elapsed chart time, I had this thought: As the ultimate plant threat, I would get a match and burn the plant’s electroded leaf. At that time, the plant was about fifteen feet away from where I was standing…The only new thing that occurred was this thought.
The very moment the imagery of burning that leaf entered my mind, the polygraph recording pen moved rapidly to the top of the chart! No words were spoken, no touching the plant, no lighting of matches, just my clear intention to burn the leaf. The plant recording showed dramatic excitation. To me this was a powerful, high-quality observation…I must state that, on February 2, 1966, at 13 minutes, 55 seconds into that chart recording, my whole consciousness changed. I then thought, ‘Gee, it’s as though this plant read my mind!'”
