The effect of deja vu (from the French. Déjà vu, “already seen”) is very common. Psychologists say that about 97% of people experience this condition at least once in their lives. When deja vu man it seems that the situation in the present repeats the one in which he had once been, and he clearly realizes that this is impossible. There is a certain removal from reality, there is a simultaneous “living” of events in the past and in the present. The experience is so strong that it leaves an indelible mark on the memory. Some people consider the deja vu phenomenon a sign of mental deviations and do not dare to share their experiences with relatives for fear that they will be considered unbalanced. In fact, the deja vu phenomenon is neither a disease nor a symptom of any health problems. Most scientists consider it a consequence of the kind of “pranks” of the brain that arise when processing information. The immediate causes of the phenomenon have not yet been elucidated, but the types of déjà vu, which we will discuss in this article, have been studied.
1. Deja veku
Déjà century (from the French. Déjà vécu, “already experienced”) is a more detailed version of the deja vu. In this state, a person not only believes that he has already got into the current situation, but also “remembers” it in the smallest details. It seems to him that he will recognize sounds, smells, tactile sensations and can foresee events that will happen in the near future.
2. Deja visite
A kind of deja vu associated with spatial sensations (from French. Déjà visité, “already visited”). This condition is familiar to many. For example, you come to a foreign city, knowing full well that you did not have the opportunity to study it before, nevertheless you “recognize” houses and streets and you can even find the most convenient route between two objects without problems.
3. Deja senti
Unlike other varieties of deja vu, deja senti (from the French déjà senti, “already felt”) does not leave a person with the impression of “incorrectness” of his own reaction to the events. He just feels a passing sensation of recognition, triggered by smells or sounds. Most often, deja senti occurs under the influence of a human voice or music, as well as during reading.
4. Jamais vu
The phenomenon opposite to deja vu. When Zhamieva (from the French jamais vu, “never seen”), a person does not recognize the situation or the place where he has fallen, understanding that in reality both the place and the situation are familiar and familiar to him. Variants of zhamevyu are known when people of relatives and friends seem completely alien to people.
5. Presque vu
A very unpleasant and obsessive state, perfectly described by the expression “turns on the tip of the tongue” (from the French. Presque vu, “almost seen”). Familiar information (word, name, name, etc.) seems to be instantly forgotten. It feels like quite affordable, but it does not manage to “grab”. In this case, a person usually has an erroneous assurance that he knows exactly which letter or syllable the forgotten word begins with.
The state of the presquite causes discomfort, and its ending (as sudden as the beginning) is perceived with great relief.
6. “Wit on the stairs”
A situation familiar to almost everyone: right after an important or too emotional conversation, successful objections that did not come out in time come to mind (from the French l’esprit de l’escalier, “the spirit of the ladder”). At the same time, a person is usually annoyed with his own inability. In fact, intelligence has nothing to do with it. Just an overexcited brain cannot immediately move on to solving new problems, but re-loses the events that have already happened, going through possible options for their development.
The deja vu mechanism has not been fully studied, but it has been established that the state has no direct connection with mental disorders, although it can occur with them. For most people, deja vu occur extremely rarely. Presumably, the likelihood of their occurrence increases with fatigue or severe stress. In any case, you should not be afraid of deja vu.
