Meaning of Déjà vu
What is Déjà vu:
Deja vu, also called as the psychology of deja vu, is called the experience of feeling familiar with a new moment that we are living.
The word comes from French and is translated into Spanish as "already seen." The term was created by the French psychic Émile Boirac in the early 20th century.
As such, the deja vu It is a sensation that occasionally arises between 10 and 30 seconds. They are considered hallucinations or false memories and occurs when we do, say or see something that gives the feeling that we have seen or done it before, but that, in reality, never happened.
Thus, the deja vu it is presented as a kind of repetition, where a person has experiences that they are sure have happened before.
In psychology, the name formally given to deja vu It is paramnesia, which refers to the psychological reaction resulting from an alteration of memory, because of which a person believes that they remember situations that have never happened.
The deja vu it is a normal feeling of temporary strangeness of having lived the same moment in the past and does not carry any violent symptoms such as seizures. A clear example of deja vu It is when you visit a place long after you have seen a movie that showed the same setting.
Scientific explanation of deja vu
The deja vu occurs as a result of a technical problem in the brain, a memory abnormality, where the events that are happening are stored directly in long or short-term memory, when the correct thing would be to go to immediate memory, thus giving the impression that the event has already happened before.
The deja vu It occurs because the brain has several types of memory that are confused in a particular situation. Our memory is divided into three types:
- immediate memory, which is capable of repeating a telephone number and then forgetting it;
- short-term memory, which is made up of events that are perceived as belonging to the present, and which lasts a few hours;
- long-term memory, which are events that are perceived as belonging to the past but that can remain in the memory for months and even years.
Types deja vu
There are several types of deja vu depending on the type of situation with which the memory impairment is related. Some of the most common are:
- Let me visit or, in Spanish, ‘already visited’: psychological reaction that causes the brain to transmit to the person that it has been in the place where it is now, even though it has never been there.
- Let me feel or ‘already felt’ experience of feeling something that has already been felt.
- Déjà vécu or ‘already lived’: feeling of having experienced the same situation before. It is the most common of the three types of experience.
