Have you ever zoned out, because you're thinking too hard, or maybe not thinking at all. And your eyes go kinda fuzzy, and you feel calm. You are not thinking about what you're staring at. You feel calm. You can feel your pulse, and your chest rises up and down. It's like everything is okay for a moment. Then you blink, and your calm world is gone. Ripped out from under you. And you're back in the real world.
