When I was a kid, I’d see severed heads floating in the dark. Every night my mother would scratch my back, kiss my forehead, say I love you, then shut off the lights. It would usually take a long time to fall asleep, and sometimes the dreams were good, but once or twice a week, the heads would squeeze through the cracks in the walls or descend from the ceiling. They’d surround me, wan and stiff and misshapen. They liked to watch my skin change color, from calm olive to tousled red to chilly white, and the way my lungs would seize up when they drummed their stumpy necks on my chest. They liked even more that I’d weep, silent and catatonic, hapless in the fog of my unconsciousness.
