Why there is a deja vu effect?

For sure, at least once in your life you have the effect of deja vu, the feeling that everything that happens in real reality, is repeated, and you in advance for a few moments or seconds know what will happen next. Perhaps this feeling you have occurs quite often or even haunts you, in fact, for this reason, you are likely to be interested in why it occurs.

This unique phenomenon by its nature carries some mystery of the unknown and mystical. But is it really mystique or a normal process of brain activity?

In the book" Psychology of the future " the famous psychologist Emil Buarak first used the term "deja vu" (which means "already seen"). Previously, this phenomenon was characterized as" paramnesia "- memory deceptions in violation of consciousness or as"false recognition".

Currently, this phenomenon is still not fully understood and is of increased interest not only from ordinary people, but also scientists, psychologists, magicians and sorcerers. There are several assumptions about what exactly is the effect of deja vu and why it occurs.

In addition, there is also the opposite phenomenon, which is called "jamais vu" and characterizes the opposite effect – not recognising familiar things or people. This phenomenon is different from the well-known memory loss so that this effect occurs suddenly. For example, during a conversation with your best friend, you just catch yourself thinking that you are not familiar with this person and do not know anything about him. Common practice of "jamais vu" is very rare, but is still the place to be.

In 1878, scientists suggested that the effect of deja vu occurs due to fatigue, when the processes of perception and awareness are disturbed. In other words, in response to the question "Why there is a deja vu effect" according to scientists, the first assumption can be made that this occurs due to fatigue, congestion or fatigue.

Absolutely the opposite opinion was put forward by William H. Burnham (American physiologist) in 1889. He argued that this phenomenon occurs as a result of active brain activity, when the processes are much faster. He said that this is more likely to happen after a good and productive rest, when the mind and mind are clear, the brain thinks much faster and better, and so the person is able to see the situation as if it is familiar to him.

There is also a version of the fact that the effect of deja vu is quite closely related to dreams. In fact, most people who have had to experience this condition, tend to believe that what is happening has seen in a dream. But this hypothesis scientists do not reject, and in 1986, Professor of psychology Arthur Allin suggested that the effect of deja vu – a kind of forgotten dreams.

The well-known Sigmund Freud also became interested in why there is a deja vu effect and put forward his version. In his opinion, the effect of déjà vu is no more than a person's subconscious fantasies that arise spontaneously.

Also in psychology there is an opinion that, by the way, today it is important that the brain has areas responsible for the past, present and future. Since there are no clear boundaries and time frames, this may be the cause of this phenomenon.

But be that as it may, the effect of deja vu is still actively studied by scientists and psychologists. Even the fact that there is no clear and unambiguous opinion on this matter, one can say for sure that the effect of deja vu does not pose any danger to humans and does not bear a negative color. Therefore, we can only guess the reasons for this feeling.
