Deja Vu

This will be the first ever post I upload from my phone, so please excuse any misspellings.

Well I was wondering about the occurrences of Deja Vu. What do they mean, exactly?
Deja Vu is when you feel as though you've experienced an exact moment before, is it not?

I've watched this movie before that gave a very interesting and plausible explanation of Deja Vu. I've forgotten the name.. Haha.. =_=
The movie's theory is that Deju Vu is something that we of another time dimension have gone through before, that's why we get the "familiar" feeling of Deja Vu.
We have to make choices all the time, be it choosing our clothes or be it deciding on the food we eat. All these decisions will lead to our future. Meaning if we had made another choice, our future will change.
The movie says that there are many dimensions of time, and in each one we many different decisions and therefore have different futures.
So perhaps you're doing something and suddenly you get a sense of Deja Vu. According to the movie, the 'you' on the other dimension have already experienced the exact scene you were in, and therefore you feel Deja Vu.
Creepy, but cool.

I personally think that this is a very plausible theory. However, I do not believe in other dimensions.

My own theory is that we have dreamt of that exact scene before. It does happen, because I've experienced it twice before. I can only say twice because on other occasions I forget my dreams. Most of the time I forget if even dreamt.
I am a christian, and I believe in God. My theory is that God has sent me these dreams for a purpose. To tell me good news? To warn me? Well I don't know.

This is my own theory and I'm just sharing. I do realize that religion is a touchy subject, so don't be offended or anything this is just me.

The end!
