Looking for inspiration in all your usual places but coming up empty? Cameron MacKenzie, author of "The Beginning of His Excellent and Eventful Career" and "River Weather," suggests using your dreams to get you started on a new writing project. He takes us through his process of using one line to create a story, and how your unconscious brain can give you the best ideas. Take yourself seriously, he argues, even when you're not aware of what your self is up to.
