What will I do when you are fallen asleep?

Question
May Swenson

Body my house
my horse my hound
what will I do
when you are fallen
Where will I sleep
How will I ride
What will I hunt
Where can I go
without my mount
all eager and quick
How will I know
in thicket ahead
is danger or treasure
when Body my good
bright dog is dead
How will it be
to lie in the sky
without roof or door
and wind for an eye
With cloud for shift
how will I hide?
