The question echo in your empty mind. You can't think of anything, you can't do anything. Blackness. Blackness everywhere...
You remain floating in that darkness for an unknown amount of time. It could be seconds, it could be months. Time here has no significance.
At some point, sometimes, you see among that complete darkness the smallest of point - a bright light. As you focus on it, it grows larger and larger until everything is white.
It is at this point that you finally breathe.
