This may lead to unpleasant consequences. Hearing, taste, vision - and in general, our brain is subject to deceptions, and there are those that cannot be distinguished from reality. Hallucinations are just such an example - whether auditory or visual, they occur for various reasons. Sometimes it's just a small "misfire" of our body, and in other cases - a dangerous phenomenon. They can occur in a variety of conditions such as psychosis, drug intoxication, medical conditions such as migraine or epilepsy, as well as lack of sleep or extreme stress.
Some studies show that about 10-15% of healthy people experience hallucinations periodically. Hallucinations are the result of a disruption in the normal functioning of the brain and can be caused by a variety of factors. Some of these may include brain damage, changes in chemical processes, sleep and wake disturbances, and mental illness.
Hallucinations can be very realistic and can sometimes be triggered by memories or desires.
The scientific explanation for hallucinations has to do with our brain function. Thoughts and perceptions are associated with electrical activity in the brain. When this activity is disrupted, we may begin to perceive things that are not there. It can also be caused by stress, fatigue, or even certain medications.
For example, activation of dopamine receptors can cause distortions in visual perception, and changes in the functioning of other neurotransmitters, such as serotonin or gamma-aminobutyric acid (GABA), can also contribute to their occurrence.
Although hallucinations are often associated with drugs, they can also be produced without drugs, for example, as a result of simple brain hyperactivity.
Some diseases, such as Parkinson's disease, Alzheimer's disease and bipolar disorder, are also associated with hallucinations - this not only worsens the course of the disease, but also significantly complicates treatment.
But one of the most dangerous are auditory - the key point in determining the danger of auditory hallucinations is the content of the voices that a person hears. Voices can be benevolent and encouraging, but they can also be angry, threatening and even call for violence. When voices become a call to violence, it's definitely not a good sign.
