Probably some of us felt as if we were already in this place, although we were sure that we had never visited this city, or that the conversation was already present, but where and when, it’s impossible to specifically recall. This phenomenon is called the deja vu effect.
In a literal translation from French, deja vu is interpreted as "once experienced, " "previously heard, " "never seen." Generally speaking, deja vu is such a state in which people feel as if they had already been here before.
Why does the deja vu phenomenon occur?
Despite a lot of research, scientists cannot come to an unambiguous opinion, research is ongoing, scientific debate, new versions are emerging. The whole complexity of the experiments lies in the fact that it is impossible to simulate the artificial situation of deja vu.
From a medical point of view, the effect of deja vu is associated with a malfunction in the brain, or more specifically, its temporal lobe, which is responsible for similar human thinking. In the temporal section, memories are associated with events taking place in our time. The reason for the failure of the brain, scientists believe mental fatigue, increased physical fatigue, increased depression and so on. In addition, neurologists believe that the deja vu effect can be triggered by natural changes, for example, increased solar activity, severe frosts, sweltering heat or a sharp decrease / increase in atmospheric pressure.
What is the deja vu effect and why does it occur?
There are three main versions of the occurrence of the effect:
- According to esotericists, the deja vu effect is the receipt of information sent by our ancestors. But how can one get information from the ancestors, if they were not 100% likely to be in this place and could not even imagine the real events?
- it is believed that a person, getting into a difficult situation, is trying to find a way out or various solutions to problems. The brain cannot cope and find suitable solutions and invents new ones, but through the effect of deja vu gives them away as old, already familiar;
- short-term contact with parallel reality or time travel.
Despite the contradictions of all versions, scientists are inclined to believe that the brain even in a dream forms a model of this or that behavior, in a particular situation, and when a similar situation happens in reality, that person perceives it as repeating.
