All things are interconnected. Dreams touch real life almost as frequently as real life touches our dreams. Are those events which I dream of as I slumber real? Do I laugh, live, love, murder, and save in reality, as I dream of such occurrences?
We all do, you see, because the dream is no more unreal for its immateriality than a story is unreal simply because it is fiction. It matters, that a story fit together right, because the story is a reality. These characters, the things that they do, and the things that happen to them are all important, and real. The fact that they lack a body of meat and bone does not make them somehow less than you or I. This is why motivation matters. Spectacle has its place, certainly, but every time a character acts in a way wholly contrary to her nature, the world in which she lives breaks ... a little.
Do not dismiss the fictional as unimportant, or somehow less real. They have been imagined, life has been blown into their existence, and a world has been woven around their existence. They matter.
