Interpretation of Dreams

I get dreams almost daily. I never cared to interpret them. I heard someone say dreams don't repeat. But once in a blue moon I get the dream of a fighter plane or alien spaceship crash into my neighborhood I cannot say it is the same dream but the theme of the dream is same. I did some research and found that a dream is just pictures and not a movie, when we wake up the brain makes a story out of those pictures. I can't fathom why I always feel that I see the live dream while its just pictures. May be the frames of the dream picture are at a slow rate and the brain boosts it and adds graphics and makes it watch able.  So there are two departments one makes pictures and the other edits it. Now why do you remember some and forget the others? May be it’s because not all the films are hits, you remember only those dreams that are hit you forget the flops. This also answers why dreams don't repeat!
