In Dramatica Story Theory, “Mind” is an internal state, describing problems which come from fixed attitudes. When Mind is chosen as the Objective Story Domain, the problems that affect all the characters will stem from internal attitudes and fixations. For example, an Objective Story Domain of Mind might be about how prejudice affects a town or how a humiliating memory affects a kingdom. In contrast, Universe and Physics Objective Stories deal with external states and processes. A selection of Mind as the Objective Story Domain specifically means that the source of the difficulties between all the Objective Characters is best seen as a problematic state of mind.
