Psychological state of the person under the name of a deja vu till today remains mysterious. This phenomenon attracts interest of official medicine, psychology, science and various esoteric currents. All of them put forward the versions and statements what the unusual feeling is and why the effect of a deja vu appears.
Why there is a feeling of a deja vu?
Each of us heard about this phenomenon, and most of people at least once in life managed to test it. Events which take place in reality at present cause feelings that all this very familiarly and already once occurred in life. However, as a rule, the person cannot remember specific details from the events, and there are only vague feelings with a short duration, literally several seconds. The person hardly manages to realize that happens to him as this feeling disappears at once. It is called effect of a deja vu.
Already seen – this term is so translated from French. It was for the first time used by the psychologist Emil Buarak (1851-1917) in his book Future Psychology. To study this effect quite difficult as it belongs only to human feelings. To make experiments in this area it is extremely difficult and unsafe because some interventions can deprive of the person of hearing, sight or at all to make paralyzed. Besides this feeling is not controlled, and it is artificially possible to cause it only under hypnosis. Therefore definite answer to a question why there is a feeling of a deja vu remains not solved still. However experts allocate some variety of reasons on which the person can have mysterious feeling.
Causes of a deja vu
- Images or feelings which were in a dream coincided with reality. It is, perhaps, the most common cause on which people test effect of a deja vu. In a dream we quite often can see situations very close to reality. Our brain models dreams, proceeding from real memoirs of the person, his feelings and experiences which can be realized over time, causing feeling of a deja vu.
- Already seen it appears the real reminiscence. Even if we did not pay attention to something and passed by consciousness, our brain continuously obtains a set of various information, postponing it in subconsciousness. After the person faces it already consciously, at such moments and there are that vague feeling and memoirs as if it already was. For an example it is possible to remember a case from the movie Shurik's Adventures when it was too plunged into preparation for examination and did not pay attention to what occurs around including a campaign to the unfamiliar girl home. Then having appeared there again, he had that feeling of a deja vu.
- Manifestation of false memory. In certain fields of work of a brain there can be some failure, and it for several seconds begins to take unfamiliar situations for already known. It is necessary that this process of failure most often happens aged from 16 up to 18 and from 35 to 40 years.
- Parapsychologists claim that the deja vu has very mysterious and even mystical roots. It is connected with the fact that people, presumably, live not one life, and a little. Owing to what, some episodes of one of them can unexpectedly recur to the memory.
It should be noted that at the moment so far any of the versions considered by scientists why there is a deja vu, is not recognized officially. This imperceptible phenomenon which difficult gives in to a research, study and till today.
