I dreamt I was brazing a frame that kept changing its own geometry

I'm at my bench and every time I go to tack a joint, the tubes shift a little on their own — the top tube gets longer, the seat angle relaxes, the bottom bracket drops. I keep trying to hold it in place, and then at some point I just let it move, and the frame starts humming like a tuning fork. When I woke up I couldn't decide if that meant I'd finally learned to listen or if I'd just stopped caring. Maybe those are the same thing after all.
