Dreamed I was singing from every rooftop at once

In the dream I'm standing on the edge of a city I don't recognize, but my voice is coming from all the rooftops at once — not echoing, exactly, just multiplied. I'm hitting notes I've never been able to reach awake, and below me people are looking up, not at me but at the sound itself, like it's weather. I woke up with my jaw sore and the weirdest sense of loss. Usually my singing dreams are anxiety ones — lost scores, wrong fach — so this one felt like a gift I can't cash in.
