Even perfectly healthy people can start to see hallucinations, if you create the right conditions for this
Sometimes our brain can do funny things. Take, for example, a study in which researchers took 13 people, blindfolded for 96 hours (ie, 4 days), and recorded everything that "saw" these people. In the ten participants in the experiment began visual hallucinations, some of them were very intense and vivid. Many hallucinations consisted of simple lights, some were more complex. But in each case, the participants knew that all this is just a figment of their imagination.
Here is what one of them says: "Hallucinations started somewhere 12 hours after blindfolding, and turned into a series of different images, as if in a dream." Another participant said that she saw a butterfly, has turned into the sunset, I saw an otter and a flower. She also saw the city, the sky, and the lions. All these visions were so vivid that she could hardly look at them. If it was a sunset or sunrise, then watch the sun was impossible because it was incredibly bright.
Here is the opinion of the authors of the experiment:
All 13 subjects who voluntarily agreed to long visual deprivation were perfectly healthy people who have not been cases of cognitive dysfunction or psychosis. Also they had no ocular abnormalities. They wore specially designed bandages, and experts in the experiment recorded their feelings on tape. Ten subjects (77%) reported visual hallucinations that were as simple (in the form of bright spots of light) and complex (decorative objects, landscapes). In most cases, hallucinations began after the first day of visual deprivation. Subjects were aware of the fact that their vision is not real. This experiment clearly demonstrates that rapid and complete visual deprivation is enough to cause visual hallucinations have absolutely healthy subjects.
One subject, a 29-year-old woman saw a hallucination after 12 hours of deprivation. This happened at a time when she stood before the mirror. It was during this time she dreamed green face with huge eyes, which is very scared of her. Another 24-year-old woman reported that her hallucinations were one and the same event. She felt that she was dozing, waiting for her sister to come. When my sister finally came into the room, she noticed that her eyes instead of spots of light.
