We explain to you what is deja vu and the conclusion that science has reached on this term. In addition, the types of deja vu that exist.
What is deja vu?
Have you ever felt that a scene or act that you are going through in your life have you already lived through? This strange sensation is called D jj vu and there are several explanations and characteristics to describe this event.
The word D ja vu has its origin in the French language where its meaning is " already seen ", and its main definition explains that it is an experience we feel when we believe that we have witnessed or experienced with Previously a certain situation that is new. That is, the person who has a d djj vu will find himself with an intense sensation that a certain act that is lived today has already lived it at some time in his past .
However, in order to explain this strange sensation, psychologist Edward Titchener affirmed that this occurs when the person perceives a certain vision before the brain is able to finalize the construction of perception in a conscious and total way of that particular circumstance.
When we go through this sensation of D j vu, we also experience feelings of despair and impression because the brain is not able to place the sensation in space and time that supposedly has already been lived. In addition, this sensation does not usually last more than a few minutes because it then fades away, leaving the person who has just suffered it with a bewilderment about whether the experience was a kind of dream., also, a premonition.
Both in antiquity and for those who believe in superstitions, these sensations are considered as something paranormal and their analysis will depend on the beliefs that each person possesses.
It is said that more than 60% of people have experienced this sensation more than once in their lives. Because it is practically impossible to recreate this sensation in a laboratory so that scientists can analyze it, hypnosis has begun to be implemented in order to recreate the D j vu .

What does science say about deja vu?
After several investigations, both psychological and neurological, it has been concluded that déjà vu is an anomaly produced by the brain . This means that it is an impression of an experience that is believed to be remembered.
This argument is based on the fact that every time a person goes through this feeling, the detailed information of that "memory" is usually quite uncertain ; people are not usually able to decipher where, when and how this happened. After a while, the person will not be able to describe what caused the déjà vu.
Types of Déjà vu
- Déjà vécu: this type of déjà vu is the one that people normally refer to. It is that feeling that we are witnessing it, saying or seeing it, we have already experienced it before. Studies have shown that they usually occur more frequently in young people between 15 and 25 years of age, because their minds are still subject to notice any change in their environment. What characterizes it in an essential way is that the experience that is believed to be lived usually includes a great deal of detail in common with the memory referred to.
- Dejà senti: Unlike the déjà vècu, this process is only a mental process. That is to say, it does not have any cognitive characteristics nor does it usually refer to the memory of the person who crosses it. In addition, one could say that it can be a sensation that brings satisfaction because something that has been forgotten in our minds for a long time is remembered.
- Déjà visited: It can be translated as "something already visited", that is, this process refers to a knowledge that has about something totally new for the person. That is, when you know a place or something new that there is no reason why you can get to know it. Some explanations that allude to this phenomenon are dreams, extracorporeal trips and, in addition, reincarnation. As for a more skeptical analysis, it is said that it is likely that prior knowledge that is of great depth about a place, for example, may cause this sensation.
