Question

What is the main "theme" of the following piece:
"The Death of the Ball Turret Gunner," by Randall Jarrell.

From my mother's sleep I fell into the State, And I hunched in its belly till my wet fur froze.

Six miles from earth, loosed from its dream of life, I woke to black flak and the nightmare fighters.

When I died they washed me out of the turret with a hose.


He is dreaming

The fact that his death is of no importance

He is flying from Earth

He is having a nightmare
