After all, this was Opéra Garnier, inspiration for The Phantom of the Opera. It was often that the air stopped completely in certain corridors, and we all heard the ghostly footsteps that accompanied walking the halls alone. There were strange doors in the dressing rooms that didn’t open and tunnels beneath the stage, and no one knew where they went. We didn’t know what lay in the pools below, and just earlier that day, I’d sworn shadows flickered in the corner of my vision. We seldom talked about it aloud—if you asked an older dancer, you’d only be met with the same advice: Ignore it.
