Deja vu is one of the most mysterious and little-studied phenomena of the human psyche. Most people at least once in their life have come across the fact that, getting to a completely new place, they began to experience a strange feeling of confidence that they had been here before. Or, for example, met people whose faces seemed very familiar. All this has already happened, the only question is - when?
The meaning of the word "deja vu" from French translates as "already seen." This is a certain mental state associated with the feeling that you have already been in a similar situation. At the same time, the deja vu effect is not associated with a specific moment from the past, with an already experienced situation; rather, it refers to the past tense in general. And this phenomenon, according to numerous studies, is quite common. Modern psychologists believe that about 95-97% of people experienced the feeling of "already seen" at least once.
The reasons for this phenomenon are not exactly established. Some believe that deja vu is a phenomenon caused by processes in those areas of the brain that are responsible for primary perception and memory. According to this theory, the information received by a person in some cases is first remembered and only then begins to be analyzed. Thanks to this “reverse chain”, the brain, comparing the situation with its copy in memory, comes to the right conclusion that it already was.
Physicists say that deja vu is a phenomenon associated with the yet little-studied characteristics of time. According to their theory, the present, past and future exist simultaneously. However, the consciousness of modern man is able to fully perceive only what is called "here and now." Thus, the brain “loses” part of the perceived information. Official science is not yet able to give a clear idea of exactly how this mechanism works, and for a person this issue contains a lot of secrets.
Psychologists attribute the occurrence of the deja vu effect to the thin-planed energy permeating the entire Cosmos. Studies have shown that the process of thinking is, first of all, the process of generating electricity, which has certain informational characteristics. Experts in the field of psychology call this spiritual, mental energy. Thanks to her, in their opinion, some people with hypersensitive perception see thought forms in the form of fields of different colors. Depending on the energy pump, they can be weak, medium or strong. The latter are able to leave the so-called information traces, forming a rather powerful focus of excitation in the brain. They can be superimposed on each other, spontaneously transferred in time and space and return back to their source. Thus, the deja vu effect is simply the result of exposure to the information that has returned to the person from another time.
Obviously, there is still no single explanation for what happens in the mind at the moment of deja vu, how the latter is born and what are its causes. However, it is clear that this phenomenon is not a mental anomaly and does not belong to the category of diseases or deviations, and therefore you should not worry when encountering it. This is just one of the capabilities of the human brain, not yet fully understood by scientists.
