The rock bottom is a quiet place. Sun rays can reach every planet in our solar system, but they dissolve hundreds of feet above your head, and so you sit in total darkness. You can feel that the sea bed under your body is cool and sandy. You tap the ground around you delicately, and you find two things - a little rock, and something smooth and oblong, like an old bone. There's no noise, either. Somewhere up above waves the size of skyscrapes blow up and crash like a city during war, or maybe today they're little and elegant. You don't know. You're at rock bottom. Then a glimpse of light catches your eye - it's a tiny pink jellyfish that glows in the dark. It's not really swimming though, it's mostly floating in place. It's a very different world from the one you know, but you're not ready to move on just yet.
