The word Déja vu has its origin in the French language where its meaning is " already seen " , and its main definition explains that it is an experience that we feel when we believe that we have witnessed or have previously experienced a certain situation that is new. That is, the person who has déjá vu will find an intense feeling that a certain act that is experienced today has already been experienced at some point in the past.

However, in order to explain this strange sensation, the psychologist Edward Titchener affirmed that this occurs when the person perceives a certain vision before the brain is able to consciously and fully complete the construction of the perception of that certain circumstance.

When we go through this sensation of Déjà vu, we also experience feelings of despair and shock because the brain is not able to locate in space and time the sensation that has supposedly already been experienced. In addition, this feeling does not usually last more than a few minutes because then it fades, leaving the person who has just suffered it with a bewilderment about whether the experience was a kind of dream or, also, a premonition.

Both in ancient times and for those people who believe in superstitions, these sensations are considered paranormal and their analysis will depend on the beliefs that each person has.

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 for scientists to analyze it, hypnosis has begun to be implemented in order to recreate Déjà vu .

What does science say about deja vu?

After a while, the person will not be able to describe what caused the déjà vu.

After several investigations , both psychological and neurological, it has been concluded that déjà vu is an abnormality produced by the brain . This means that it is an impression on an experience that is believed to be remembered.

This argument is based on the fact that each time a person experiences this sensation, the detailed information of that "memory" is usually quite uncertain ; people are usually not able to decipher where, when and in what way this event occurred. 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 what people usually refer to. It is that feeling that we are witnessing it, saying or seeing it, we have already lived it before. Studies have shown that they tend to occur more frequently in young people between 15 and 25 years of age, because their minds are still subject to notice any type of change in their environment. What characterizes it in an essential way is that the experience that is believed to have been lived usually includes a large number of details in common with the memory to which it refers.
  • Stop feeling. Unlike déjà vècu, this process is only a mental process . That is, it does not have any cognitive characteristics nor does it usually refer to the memory of the person who goes through it. In addition, it could be said that it can be a feeling that brings satisfaction due to remembering something that has been forgotten in our mind for a long time.
  • Déjà I visited. It can be translated as "something already visited", that is to say, this process refers to a knowledge that one has about something totally new for the person. That is, when you know a place or something new there is no reason why you can get to know it. Some explanations that are alluded to for this phenomenon are dreams, out-of-body travel and, in addition, reincarnation. As for a more skeptical analysis, it is said that it is likely that previous knowledge that is of great depth about a place, for example, can cause this feeling.
