“There’s something covering my face, I can’t breathe, I’m suffocating. When I surface into wakefulness, I’m gasping for air and my chest hurts. I sit up, eyes wide, and see something moving in the corner of the room, a dense centre of blackness that keeps growing, and I almost cry out – and then I’m properly awake and there’s nothing there, but I am sitting up in bed and my cheeks are wet with tears.”
