Horror is the fiction of worst-case scenarios. And the art is in giving it a mythic, symbolic, resonantly recognizable image to grapple with. A monster, a shadow, a mirror reflection. A something. And we face it, then deal with it or don’t. As for literalization—if I understand what you’re asking correctly—yeah, I tend to wade in face-first with a wide angle lens, shooting the dream in my head with as much intense visual specificity as possible.
