My friend came up with this and tohught it was so epic i would share it with you.
I finally understand what happened to Leonardo Dicaprio in titanic, since he was the main character he obviously couldn't die, it was really just a dream and when he sunk underwater it was really him falling into limbo and he finally gets out of it which is the beginning of inception when he is finally out of the ocean. so really its true inception: a movie within a movie.
