Apartment pool

[71degrees]

By the window,
a child wakes from the light.
Stirring on his mattress,
he watches the walls of his room
live & die
live & die
from the strange electric glow,
still dancing in rhythm
to the hiss of the city night.

Am assuming the repetition of "live and die" is supposed to mimic the undulation of the pool light. Why would a "child" give consideration to this comparison? Children don't think in these terms. Phrases like "stirring on his mattress" don't add much. "electric" is a strange adjective also. Again, not sure a child would make this connection. There's something here but not sure what you are trying to convey to the reader.
