If you have ever had the feeling of finding yourself in a familiar situation, which you think you have already gone through, but you are sure that it is not like that, then you have experienced déjà vu , as this phenomenon is called from its name which derives from the French “already seen”.
Indeed, it is a curious perception that certain people have more often than others, although all of us, to a greater or lesser extent, know what déjà vu is. But why does it happen?
First of all we can say that it is estimated that 3 out of 4 human beings have a déjà vu regularly , and always with the same characteristics: the idea that this situation has been experienced in the past, even when it comes to completely new circumstances. .
It occurs without any other indication previously anticipating it and, from what is known so far, there are no specific causes that can explain this striking situation.
Now, science has been in charge of classifying déjà vu into three different types of them:
- Déjà vécu: the purest definition of déjà vu is this, since it refers to the feeling that we are going through a situation already experienced, hence the literal translation.
- Déjà senti: they feel the same emotions as at some previous moment, although it is difficult to pinpoint exactly when those emotions were generated.
- Déjà visited: the manifestation of having been to a particular place before, such as a city, even though we have never been there in our lives.
Why does déjà vu happen?
The origin is undoubtedly in the brain, and scientists have concluded that we go through this instance when the temporal lobe, the circuit responsible for the appearance of memories, is activated at a time when it was not really required Your presence. That is, we could say that it is the result of a failure.
On the other hand, there are certain triggers for this phenomenon, such as stress , the most imaginative or creative minds, also those with higher than average intelligence; and evidence that they are more common between the ages of 15 and 25 than during adulthood.
Then, of course, there is no lack of non-scientific explanations, such as those that associate déjà vu with movements in the field of the paranormal , but that cannot present reliable evidence.
