Antagonistic hallucination (can also be found hallucinatory-antagonistic) - a type of hallucination consisting of simultaneous optical perceptions of different images - opposing ones, sometimes with displacement of the axes, easily combined by simple searching. Mechanism of G. a. must be seen as a special disorder of the visual analyzer: when experiencing an illusion, the patient “sees” in some place several images (up to a dozen), against the background of which all the others look “faded,” and the real visible is “emphasized.” Observed in catatonic stupor. However, this theory is not recognized by most researchers into the nature of hallucinations. Most scientists adhere to the theory of emotional upheavals, according to which the patient is temporarily dominated by contrasting emotions, and this disrupts the flow of information normally extracted by the organ of vision from reality, as a result of which its volume becomes so large that in its place it becomes possible to temporarily use a hallucinatory “empty” ”, a set of visual representations (irrelevant) waiting to be filled. Clinical example: patient F., 66 years old, was mistakenly placed in a general ward. He hallucinated today, hearing threats against him. When he was transferred to the department of patients with schizophrenia, he developed bright, distinct, objective, unstable auditory hallucinatory experiences (“goose slapping”, cyanotic flowers in the window). He was happy in the department and even began to eat well. As a result of deprivation and disaster, the child begins to hear, first, monotonously crying voices: “We don’t have enough (points to the crib) when we come...” And then sometimes imperative, sometimes pleading, often clear and distinct phrases from different people - persons close to the patient: “ Calm down, take care of your health. You are very impressionable; don’t think about tomorrow, it will be difficult for you,” etc. Along with this, the patient also experiences spatially localized, irregular visual hallucinations (heboid impulsive tendencies or motor-fussy phenomena). These hallucinatory phenomena are typical examples of antagonistic hallucination.
