"September," by Linda Pastan

it rained in my sleep

and in the morning the fields were wet

I dreamed of artillery
of the thunder of horses

in the morning the fields were strewn
with twigs and leaves

as if after a battle
or a sudden journey

I went to sleep in the summer
I dreamed of rain

in the morning the fields were wet
and it was autumn
