What is hallucination?

Hallucination generally refers to a perceptual experience that occurs without objective stimulation, which means it is a subjective experience. However, there are often certain differences between the subjective and the objective. This is a serious perceptual disorder. There are many causes of hallucinations, some of which are common, including some mental illnesses. In addition, poor rest and excessive mental stress may also lead to such symptoms.

What is hallucination?

Hallucination refers to the perceptual experience that occurs when there is no corresponding objective stimulus. In other words, hallucination is a subjective experience, and the subject's feelings are similar to perception. This is a more serious perceptual disorder.

The difference between hallucination and illusion is that the former has no objective stimulus. Because the feelings are often realistic and vivid, they can cause emotions or behavioral reactions such as anger, sadness, panic, escape, and even aggression towards others. Attempts to convince someone who has a hallucination experience that they do not believe in it are sometimes futile. Hallucinations can occasionally occur in normal people. For example, when you are half asleep, you may hear or see hallucinations, which are called hypnagogic hallucinations.

Hallucinations that occur when you are about to wake up but feel sleepy are called pre-sleep hallucinations. Hallucinations can also be produced through suggestion. As mentioned in past documents, some people who were addicted to religious fanaticism claimed to have seen "Guanyin Bodhisattva" or "Jesus Christ", which does not necessarily have pathological significance. However, it should be said that hallucinations are mostly pathological. If a person experiences hallucinations multiple times, he or she should be examined promptly so that his or her psychological disorder can be diagnosed and treated to prevent accidents such as injuring others, running away, or committing suicide under the influence of hallucinations.

Hallucinations have two main characteristics:

First, hallucination is a feeling. Due to the lack of corresponding real stimulation, objective test results prove that this feeling is illusory, but as far as the patient's own experience is concerned, it does not feel illusory. Second, although hallucinations originate from subjective experiences and have no objective reality roots, some patients firmly believe that their feelings come from objective reality.

By source of hallucination

True hallucination is also called complete hallucination or perceptual hallucination. It refers to the patient's experience of hallucinations that are perceived through the senses, which do not actually exist, originate from objective space, and are "real", vivid and lifelike. The patient has an unshakable belief, accompanied by corresponding thinking, emotional and volitional behavioral responses. Pseudohallucination: The hallucination image is not clear and vivid, and it occurs in the patient's subjective space, such as the brain or body. Hallucinations are not obtained through sensory organs, such as hearing voices in the stomach or seeing a figure in the head without using one's own eyes. Although the image of the hallucination is different from general perception, the patient is often very sure that he has indeed heard or seen it, and therefore firmly believes it.
