I'm a few years into writing, and I've noticed that several characters that have been with me from the beginning have, quite literally, taken on a life of their own. What I mean is that, without any conscious thought on my part, I add new characteristics to them, characteristics that slide into place as though they should have always been there. Habits, hobbies, moral fiber, and much, much more, seems to develop dynamically as I write, as though the character him or her self has tapped me on the shoulder and told me what should be written. I've heard of several people claiming that Middle Earth existed before Tolkien wrote a word, and I find the comment funny, after experiencing this. Has anyone else noticed something similar in their writing?
