Dreamt the substation was a cathedral of humming breakers

Last night I dreamed I was walking the rows of an old panel, and every breaker had a little brass nameplate like a saint's. The 60Hz hum wasn't a fault to trace, it was a choir holding one note. I went to swap out a cheap one that had failed and felt like I was committing sacrilege. Woke up still hearing that hum, and for a second I missed the place.
