Dream character. The only one I’ve seen more than once.
First time i was walking along the metal rafters of a building in order to get somewhere. It was urgent and important. This dog was there, watching and waiting for me. Whenever someone lit a match, and upon it being snuffed out, it’d transport me, asleep in a bed. I’d have to start over again, and again, and again.
Second time I found myself in a concrete room full of mirrors. The dog appeared around the corner. It seemed afraid of me as it ran down the long, darkening tunnel of mirrors.
