The psychologist Woodburn Heron wrote about this subject in his nineteen fifty-seven work “The Pathology of Boredom.” He said that the brain depends on having continuing information from the body’s senses. The mind can have problems if it has nothing new to sense. Often, the brain’s response is to create its own input, in the form of a hallucination.
A hallucination is a sensory experience that does not exist outside the mind.

Other stressful conditions can lead to Third Man experiences. These include the stress of injury or of seeing an expedition partner become injured or even die. Different scientists have studied the effects of extreme conditions on the human mind and body.
One researcher found that extreme cold can have a damaging effect on the mind. The researcher said that before the body begins to freeze, cold can cause changes in brain chemistry which lead to hallucinations.

Another doctor believes that Ernest Shackleton’s vision was caused by a drop in blood sugar. Explorers working in extreme cold often burn more energy than they can eat. This doctor believes that low glucose levels in the blood lead to hallucinations.
Another theory says that the stress of having to pay constant attention to survive leads to Third Man hallucinations.
DOUG JOHNSON:
Researchers in Switzerland were able to recreate a Third Man experience in a laboratory setting. They sent electric signals into the brain of a young patient who suffered from epilepsy. When the electric current was on, the woman described seeing a presence or shadow nearby who did not speak or move. When the scientists stopped the electricity, the woman said the presence disappeared.
