It’s interesting, how close writing is to acting. At least, in my experience.
When I’m writing a character, I feel myself slipping into their skin. My posture changes, how I sit in my chair, my facial expression, what I do with my hands.
Often, I feel the need to get up and move, just pace about, my movements channeling their imagined body language. I’ll shift into a cocky swagger, pushing my shoulders back and my chin out. Or pull myself inward, sullen like, chin dipped and peering sullenly out at the world from under a pulled-up hood. I’ll mime taking drags from a cigarette, and stare into the mirror, seeing someone else there. I can feel their emotions welling up in me, drawn from countless sources of consumed media and remembered emotions in my past. Aggression, lust, glowering anger, sly humor, wry amusement.
Music helps. The right background track, if I can find it, helps me shift into a character. And once I can fully feel the persona, wrapped around me like a cloak, I sit and I write, their speech patterns slipping from my fingers without conscious thought.
Definitely an interesting experience. I need to do more writing, explore this phenomenon.
