Another time, a writer created a protagonist who was brave and smart and deboniar--think a scientist version of James Bond. Basically, he could do anything from run a mass spectrometer to shoot a sniper rifle--and the women swooned over him.
In yet another example, a writer created an evil antagonist who ended up being the protagonist's father. And--wait for it--the next book the author wrote also had an evil father antagonist.
What do all these examples have in common? I believe the authors unconsciously revealed some aspects of their personality or paradigm. The 2nd author thinks he is like a scientist/James Bond. The 3rd author has a bad relationship with her father.
Is unconscious revelation bad? I'd say: no. As authors we have to use all the tools at our disposal, including our unconscious and our subconsious. In fact, in my experience, first novels often involve a lot of unconscious revelation.
I think this is another reason it's great to get feedback on your writing. If the reader thinks the protagonist has qualities the author didn't want him to have ==> change him! That's one of the beauties of being The Author, Great and Powerful. :)
Good luck with your conscious and unconscious revelations!
Hhm... Maybe I should go reread my first novel.
