    Hallucinations are imaginary perceptions, perceptions without an object, sensations that occur without stimuli. Hallucinations are a deceit, a mistake, an error of perception of all sense organs, when the patient sees, hears or feels something that is not actually.

    The functioning of the brain is not fully understood, namely in the unknown and the most extraordinary and mysterious is hidden. Hallucinations are from this area. The brain shows us pictures that are not. Auditory hallucinations are perceived as a voice "from above".Hallucinations have been known since time immemorial. They were given special significance. In the rituals of ancient Indians, shamans used "sacred" mushrooms to flow into the trance and evoke "visions."These mushrooms were considered divine, images and statues of mushrooms are found in ancient temples. Maya widely used hallucinogenic drugs mushrooms, herbs, tobacco, cacti) for religious and medical purposes, to relieve pain. Many famous talented people experienced hallucinations( alcoholism, opium, schizophrenia, psychosis) and at the same time gave the world new literary genres - Edgar Poe, Hemingway, Jonathan Swift, Jean Jacques Rousseau, Gogol, Yesenin, Guy de Maupassant;masterpieces of art - Vincent van Gogh, Goya;Vrubel;music - Chopin;mathematics - John Forbes Nash, Nobel laureate for developments in the field of game theory and differential geometry. Interlacing the spiritual world, the real world and the world of perceptions under the influence of the psychotic process in geniuses become unpredictable and stunning. But in the end they lead to degradation and devastation.

    Olfactory hallucinations - a sense of smell in its absence. It occurs when the temporal lobe of the brain is affected, schizophrenia. In schizophrenia, unpleasant odors are most often felt, putrid, rotten. In herpetic encephalitis, simple partial seizures, olfactory hallucinations can be combined with taste.

    Question: Can there be hallucinations in a healthy person?
    Answer: Healthy people may have illusions - visual, auditory, taste, tactile - this is a distortion of perception of the real objects of the world around them. Floating water may seem like a conversation, a hanging robe in a dark room can be mistaken for a person, an incomprehensible shadow in the twilight under a bush for animals. Illusions can also be in infectious diseases, poisoning, exhaustion. There is an illusion when an inappropriate perception is added to the perception, sensation.
