Contradictions and other Non-Opposites

I'm swimming... I am the water.
I am confused
Down below the bubbles
(those toxic tensions rising towards the air above),
we all still float, sink, and hold our cherished breath beneath the skin.
She is a shark, a serpent's kiss, a rogue molten jet of aqueous lava
boiling the water until it bathes us little fish with fire.
I am underneath the surface
unable to swim
even for my life.
