It's pretty clear to me that this song about the beauty and possibilities of art and the creative process. When you make art, you are the master of that world, and anything you imagine can be rendered on the canvas before you ("this is all ours to fuck with, this is all ours to taunt"). The character in the song also addresses and counters criticisms of being an artist. Others may say his artistic visions are "only dreams" and tell him to be more rational, but he says that a life of imagination and creativity is far better than a predictable and routinized life, taking him to places that the people who misunderstand him can't even conceive of.
