See Through Sea

I have no idea what this poem means.

Clipper ship shadow
Bottled, throttled
The 7Up green
see through sea
A fighter plane in a gymnasium
lapping the principal
And screaming
Loud, in a building
The script lifted and ripped
From his wife's secret compartment
in her music box
The tiny ballerina twirls
warbles and bows
She said someone's name
