I dreamed I was a water main inspector in a city of dogs

I was walking through tunnels beneath a city where every dog had a different kind of water pressure in their veins. The pipes were warm, pulsing, and the dogs didn’t bark — they hummed in harmonics when the system was balanced. I kept checking valves with my hands, but my fingers kept turning into roots. When I woke up, my shoulders felt heavy like they’d been carrying something underground for years. Still don’t know why.
