This is something that the novel does better than any other art form: reproducing the inner life and the inner experience of another person, particularly extreme forms of consciousness like grief, dreams, drunkenness, spiritual revelations, even insanity. Unlike movies, where we're always onlookers, in novels we have the experience of being someone else: knowing another person's soul from the inside. No other art form does that. And I like dealing with particularly intense inner experiences because I think that in many ways, this is what the novel does best.
