That's how I work, whether with stories or novels - they start with an image that comes to me in a daydream, and a lot of times I'm walking around with these pictures in my head for awhile before I start writing.
Dan ChaonPeople write fiction in their minds all the time - every time we read a 'human interest' news story, or a true crime tale, we find ourselves fascinated because we're trying to understand why people behave the way they do, why they make the choices they do, how we become who we become.
