A previous life.

A man and woman, now living apart, reunite after a long time. They sit on a bench in the shade of the trees and talk. The man speaks in a tone like he's talking to himself, about strange dreams he's been having often lately. "In some of them, I'm an animal, a plant, a tree, and a human." Even though it's a dream, it feels vividly real, as if he's become that thing. “Yeah, that's what it is... a previous life.”
