Tuning a piano in a forest of wet asphalt

Last night I dreamed I was in a parking lot at dusk, but the asphalt was damp and smelled exactly like it does after a summer rain. I was tuning a piano that had moss growing on the soundboard. The notes were coming out hollow, like they were bouncing off the ground instead of the sky. I kept turning the same pin and it never stayed. Woke up with a headache.
