Why Déjà Vu(already seen) happens?

All of us know that it is a rare phenomenon in which we feel like whatever event i am seeing had sometime happend in past time.But non of us know why this happens.Well it is due to our brain compiling many similar events and make us and create a memory similar to the event happening at a particular time.

When we experience Déjà Vu at that particular time all the events which are happening have really happend in past but at different-different period of time not at same time but it is out brain who compiled all these events of different times and made a single scene.And as the present event proceeds all the events of different times keeps recapping in out mind.

And another explanation could be that the whole event which is happening had happend in the past in a very similar way to the event happening in the present.But our brain takes both of them as exactly same as we do not remember any event as it is but have a general idea about what happend.So it is obvious that we can fell two different event as exact same.And hence Déjà Vu takes place.
