Did anyone ever wonder about this?

I just had this sudden thought yesterday while watching a movie... that basically your brain stores lots of random people's faces that you see during the day, even if you don't directly look at them or don't even notice them consciously.

Think about it this way... you walk in the city or just basically anywhere in public, lots of people pass by you and they all see you, even if unintentionally in their peripheral vision or by directly looking at you.

Now think about that in those people's dreams, a Dream Character might just use your look as their own... therefore you become a DC in someone else's dream.
Maybe someone is having recurring dreams and a DC who looks like you is an important character of those dreams...

I'm not sure how much sense this makes, but i found this to be an interesting thought ^^

Opinions?
