What is a deja vu? A lot people in any place of the world has feeling a rare sensation that comes to their minds in cuestion of seconds. The sensation be living a scene that in other past time has been lived. That odd sensation is named like "Deja vù" and is a lot common. When we talk about it phenome, and ask to other people we were surprised by the regularity wich they seems fall in it.
In that moment without notice it, we are remembering something, maybe any lost in our unconscious. But when we try to understad the reason for what this happen, the first tought is that because in other live, maybe :P, or just in other moment we could to pass a similar moment maybe a dream that we can´t remember.
Lets be clear, do you think that is impossible that it be normal? We wake almost at the same hour almost all the days of our lives, we take our breakfast the mayority of the times in a precise hour. We meet with our known people all the days, one after another. We pass in our job eight hours and in our school almost the same time every day. We pass our time with the same people, with some exceptions. So, why is so incredible that one event could repet it more that one time?
Of course that is normal, in fact, the really anormal would be that we don´t feel it. We pass a lot o events in our lives, to feel that has been lived already is obvious, at least more normal that believe that we are been in other life. XD
