Writers have to be crazy. They listen to the voices inside their head.
MontanaMan's post got me to thinking: I've talked to some people who have said — myself included here — that when they read or write, they "see" and "hear" what is described in the words upon the page. Other people have told me they neither see nor hear anything, and cannot fathom what I'm talking about; it's just words written on a piece of paper, however well-written it might be.
I wonder — how many of you see and hear the "movie," when you're reading and/or writing? How many see only the words before you? For my part, when I read I almost see what is described more tangibly than the book in front of me, though not with my eyes. I hear each character's voice differently, though not with my ears.
