The World Turned Inside Out

I once had a strange daydream that the world, from our perspective, is really inside out.  The Earth's surface forms a boundary, but instead of being on top of it, we're really under it.  The roots of trees are really the leaves, and the leaves are really the roots. Yeah, it was a weird dream.  But it was really just a different way of looking at the world.  Sometimes we get stuck in our ways, and it can be good to break out of them, if only in our dreams.
