Deja Vu Theory

Deja Vu. French. It means, 'Already Considering'/already seen'.

1 a : the illusion of remembering scenes and events when experienced for the first time.
b : a feeling that one has seen or heard something before.
2 : something overly or unpleasantly familiar.

I was talking to a sibling a week ago about it. And it occurred to me.

Forgotten Dreams.
A remembrance of a dream.

It is said that people dream everytime they sleep. But often don't remember.
I have heard: Some people have dreams, that they remember,
that tells them a bit of what is going to happen.
Such as a look at what will happen them.

A person may dream a bit of what is going to happen to them, but forget.
But when that forgotten dream is fulfilled; you get a quick remembrance of the dream.
Giving you a feeling that it has happened before.

In short: A future telling dream is forgotten, when that future happens,
you feel it happen before because you have dreamt the very thing,
there for the result could possibling be; Deja vu.

I haven't really read up all that much of it and other theories.
And this is my random thought.
