I'm thinking it's about the general feeling of restlessness and frustration. Trying really hard to get out of something (an obligation, or a box, or a cage, or something of the restrictive nature). Thrashing about as it gets harder and harder to stay patient. At the end, he runs out of energy, calms down, and resigns.
Not my style, but there's some musical quality there.
