More song than poetry, but whatever.

I am here, I am under the tree
I am under the moon and sun
the sun always burns me
the great tree always protects me
the animals are all around
the noise goes through my mind
all I can do is sit
the moon soothes me
the tree lifts me
the animals are hidden
most of them sleep silently
I can hear the words
