A bed is for remembering more than for sleeping or resting in. It soaks memories and thoughts like a large sponge, shaping itself to form along the contours of the body so that like a human, it’s always changing each day in subtle ways that accumulate to become something different.
It’s a bed he lies on at night to watch the movement of change, a bed whose shadow he sings in because he is safe. There’s nothing quite like the present, even if he doesn’t stay for very long, but it’s something that will run away if he’s not focused on chasing after his lifetime goal.
So he chases his dreams at night in another sense, and hopes that morning will come just a little later than expected.
