So often our whole world is just the things on the screen in front of us. Everything around us is filtered out and ignored.
However, every once in a while, that small piece of light ceases to be a world and becomes just a screen. The physical glass and electronics lose their status as a world and become just the physical objects. You now notice how they feel, how the borders of the device look, how it sounds to tap on it. The rest of the room comes into focus and your mind realizes that there is a world outside the room. The room, the screen, the whole world, shaped by other humans fills you with hope and sadness. You realize you live on just one spec of dust in a vast cosmos. But that spec is important and precious, because it is where you, and everyone else is. All these things are real, all have a story to tell. The people all have wants, fears, desires, but your interactions with them are superficial, mediated by tiny interactions, or just through the physical stuff they made which you interact with. You want to scream and cry from the sublime understanding of it all.
As quickly as it arrived, it is gone, the screen beckens you back and the world fades away into the background and you become immersed in the digital realm once again. Your eyes and brain filtering out everything but the screen, your fingers nothing more than a means of changing the screen, your body and mind, no longer important, is forgotten.
