Dreamt I was tuning a pipe organ that kept going out of tune on purpose

Every rank I pulled was sharp in a different spot — not sloppy, just stubborn, like the pipes had opinions. I kept checking the spec sheet and the sheet kept being wrong. Finally I gave up and just listened, and the room hummed back at me, slightly flat, and that was the right sound. Woke up annoyed that my own subconscious agrees with me about leaving things alone.
