Déjà vu

You started your day like the way every normal human being would. Having not too much to complain about or too much not to complain about up your sleeves, you went ahead to live through it like a normal day that it should be. You got into an argument with a friend of yours, and then suddenly, it all seems to look familiar.  Like that same argument, at that same time and at that sane place, had happened in the past. If you have ever experienced such, then you had experienced what is called Déjà vu. In other words, Déjà vu (French: Already Seen or Experienced) can be described as the feeling of having experienced a particular event that is upholding or that is presently occurring. 
It is the phenomenon that convinces one of having the feeling that the situation currently being experienced has already been experienced in the past. Usually, when Déjà vu occurs, we always get the idea of a place we must have visited in the past, or an action we must have done, or someone we have already seen. Most researchers have always portrayed observable reports that Déjà vu occurs as a result of a trigger by a similar brain discharge, which leads to a strange sense of familiarity. In other words, Déjà vu is caused by a strong sense of familiarity in the temporal lobe, located behind the temples in the cerebrum. 

A lot of researchers say Déjà vu is usually caused when a side of the brain gets the transmission of a particular impulse twice, thereby causing the person to sense they have experienced that exact event before. Most times, when the phenomenon occurs, it lasts for about 5-10 seconds. Stay tuned for more... Instagram: Cool_Mundial
