" In a while, one of us will go up to bed
and the other one will follow.
Then we will slip below the surface of the night
into miles of water, drifting down and down
to the dark, soundless bottom
until the weight of dreams pulls us lower still,
below the shale and layered rock,
beneath the strata of hunger and pleasure,
into the broken bones of the earth itself,
into the marrow of the only place we know. "

― Billy Collins , The Art of Drowning
