What if our dreams are just little sneak peaks of past lives we have lived, or future lives we shall live?

What if our dreams are just little sneak peaks of past lives we have lived, or future lives we shall live? 

I had a dream last night that I was driving with a friend. and we fell off a bridge into water. I knew before hand we were going to though. I just knew it. As if I had been through it before. So i opened my window and when the car hit the water I swam out. but couldn’t save him. 

Maybe that happened in a past life. Could explain the weird feeling when I am on or under bridges.
