Steeleye Span

First example:

Canal Defence Light (CDL) was a British "secret weapon" of the Second World War.

It was based upon the use of a powerful carbon-arc searchlight to dazzle and confuse enemy troops. A demonstration had shown that the use of a vehicle mounted searchlight both disoriented the units facing it and masked activities behind the searchlight.

The searchlight was mounted in an armoured turret fitted to a tank. Initially the Matilda tank was used replacing its normal turret with a cylindrical one containing the searchlight (the light emitting through a vertical slit) and a machine gun. This was later replaced by the US M3 Grant which was superior in several ways; it was a larger roomier tank, better able to keep up with tanks such as the Sherman and it had a hull mounted gun which was unaffected by the replacement of its normal turret with the searchlight turret.

The light could be varied in two ways to further enhance any effect.

• Addition of blue or amber filter would make the light source seem further away or closer respectively.
• the operation of a shutter would create a flickering effect.

The project was shrouded in secrecy. It was tested during Exercise Primrose in 1943 at Kilbride Bay with the result that it was determined to be "too uncertain to be depended upon as the main feature of an invasion".

Second:

As the abuse memories began to surface when we explored the roots of the ADD, Jim was often aware of a very bright light in the middle of the surfacing images. When I asked him to focus on the light, Jim began to repeat the same phrases again and again. One such session revealed the following set of phrases:

Your mommy loves you, no matter what anyone else says. You just fell down. Your knee is only a little scraped. Those bruises happened when you fell. Poor Jim, mommy helped you fix your knee and made it better. No matter what anyone else says, you know this is true. Your mommy loves you every day, more and more. And when you look at your knee remember your mommy loves you. Your mommy loves you more and more each day."

It took me a moment to realize that he had been told to look at a bright light while classically-formulated hypnotic suggestions were told to him after he experienced abuse. Because of this, I realized that it would be necessary to uncover all of the hypnotic suggestions that had been given to him during or after abuse.

Third:

The word, "hypnosis", comes from the term "neuro-hypnotism" first used by the Scottish physician and surgeon, James Braid, around 1841. He coined that term to differentiate his techniques from those of Franz Anton Mesmer, who named his practice "Mesmerization". It is from Braid that we get the tradition of inducing a hypnotic state by having the subject stare at a bright light.

According to Mr Tomlinson a strobe flash gun was to be shone in the face of Milosevic's driver in a tunnel causing his car to swerve and crash.

Fifth, Keel:

The mechanism—the light flashes—can be subjective, seen only by the percipient, or objective, seen by others and even photographable. The subjective flashes must be caused by radiation which by-passes the eyes and optical nerves and is received directly by the brain. Objective flashes are masses of energy moving through the visible spectrum.

If you review the thousands of UFO contact reports you will find that many of them begin with the appearance of an entity holding some kind of "flashlight" which is shone directly at the witness. In cases in which the percipient was taken aboard a saucer, a light flashes and he is told his picture has just been taken. In other instances, some of which have already been described, the entity approaches the witness and suddenly flashes a light at him which causes paralysis. Woodrow Derenberger was among the very few contact claimants who did not describe such flashes. In trying to nail down the exact chronological order of events in the contactee experience, I found that the witnesses observed the flash first and then they saw the entity approaching with some kind of flashlight. A second flash paralyzed them or rendered them unconscious. The phenomenon takes yet another form. The witness is stepping out his door, or getting out of his automobile, when there is a sudden burst of light "like a flash gun going off." No photographer or camera is visible. There is no sudden paralysis or ill effects. The witness just scratches his head in bewilderment and goes about his business. However, those who see these flashes have usually had psychic experiences previously.
