I was drowning, like 30 feet deep in a tunnel of ice leading upwards. I could see sunlight through the ice above, and so I rear up, and swim as fast as I can, using bouyancy, my muscles and determiniation to drive myself up at the thin spot at the top of the tunnel (only wide enough for myself), and I kno that if I don't rbeak through, with all this force, I'll fail and drown.
I slam into it, with everything I had behind it... and it cracks. A little. Not even enough to provide a finger hold or an air hole. Nothing. Desperate, I plant my back against one side of the tunnel, and my feet against the other, attempting to realign my position and maybe kick the top of the tunnel open- anything, I'm drowning.
And suddenly... that pressure of trying to reorient pushes NOT THE TUNNEL open, but splits the entire ice covered lake in HALF, with almost no effort. The ice splits in two, the tunnel is forgotten, and I breathe.
