A Dream, its a journey that you could not do in reality. It is like Aristotle cave man, where the cave man interpreted the world from a shadow of a fire inside the cave about what world look like, but reality its not a monochrome shadows though its reflected reality but lack of details. Therefor its half through of reality. You need to do exposure to get the depth of the details. We might want to set our aperture in order to get a correct light so things not always dark for our eyes, and we need speed to paid attention of the movement so we dont miss momentum that might an important for us to grow up, at last our journey its a composition of life, a continues fragmented frames, which at the end we realize that we already walk in the history with a guts, even just to remember it. Dare to live, dare to dream!
