Author
This may depict a part of yourself that is creative, especially to do with telling the story of your real self, your real inner passions and dreams, your life story.
An author in a dream suggests they are creative, and are a sort of author-ity.
But is the dream author really a creative person or just saying it for effect.
It might suggest ideas you have about writing, about becoming a writer, about the difficulties of doing the work. But it depends what the author is doing and what your relationship with them is.

What is it you/the author has written or is writing about, and how does that relate to your waking life?
How would I describe the character of the author or her/his abilities – and does that describe facets of myself?
Is the author ambitious or something – if so what?
