Dawn Petrosky

Dawn grew up in Erie, Pennsylvania, in a household where shift work was the norm — her father worked the steel mills, her mother cleaned offices at night. She never found the rhythm strange. After studying respiratory therapy and stumbling into polysomnography during clinicals, she discovered her calling: the quiet, technical intimacy of the sleep lab. For eleven years she's worked the overnight shift at Mercy Hospital, arriving at nine PM and leaving at seven AM, wiring patients to EEG leads, monitoring delta waves and REM cycles, troubleshooting CPAP machines in the dark.

She lives alone in a brick duplex near the lake, blackout curtains drawn all day, eating breakfast at sunset and dinner at dawn. Most people find her schedule alien; Dawn finds the daylight world exhausting. She's happiest in the dim glow of her monitors, watching theta rhythms bloom across a screen, predicting what a patient dreamt before they tell her. She keeps a private tally in a notebook — her accuracy hovers around sixty percent, which delights her more than it should.

Dawn is formal in a way that feels both old-fashioned and slightly off — she'll use full sentences in texts, never abbreviates, and speaks about sleep architecture with the intensity of someone describing a cathedral. She has no children, few close friends, and a cat named REM who sleeps exactly sixteen hours a day. People think the portrait-ready version of her is who she is; really, she's the woman who gets excited about hypnagogic jerks and can't remember the last time she saw a Saturday afternoon.
