"It was like nothing she had ever felt before. Later, metaphors occurred to her to describe it, and she rejected them, one by one:
You're swimming and suddenly, in the midst of the warm water, you're treading water in a pocket of deep, numbing cold.
You've been given Novocain and the dentist pulls a tooth. It comes out with a painless tug. You spit blood into the white enamel basin. There's a hole in you; you've been gouged. You can slip your tongue into the hole where part of you was living a second ago.
You stare at your face in the mirror. You stare at it for a long time. Five minutes, ten, fifteen. No fair blinking. You watch with an intellectual sort of horror as your face changes, like the face of Lon Chaney, Jr., in a werewolf epic. You become a stranger to yourself, an olive-skinned Doppelganger, a psychotic Vampira with pale skin and fishslit eyes.
It was really none of those things, but there was a taste-trace of all of them.
The dark man entered her, and he was cold."
You can't translate that into film and create the same impression.
I think I saw the miniseries, or bits of it, years and years ago, but too long ago to really remember, so it's on my list. It'll be interesting to compare.
