I do the same thing. I'm actually inspired by trying to talk to hypothetical instances of other people. I never did that. I normally talk to myself and to a lesser extent to my past self (when I was younger it would be my future self, but I'm currently in 'the future').

If there's a real person around I just talk to the real person, and on non-shy days this could easily be a stranger. It could make me annoying, but I also like to listen if it's about the same topic.

To me this all seems perfectly normal. My reasoning is that by activating more brain areas (i.e. Broca & Wernicke) and preferably also the pre-motor and motor cortices by moving (so walk while talking to yourself), the brain can make more connections to the content you're thinking about. That's just my hunch though.

A lot of decisions where I work are made in meetings with at least 4 or more people. The practice "conversations" are just that... practice. Dialog is more my thing than a perpetual debate club, so I'm practicing being persuasive to authorities rather than defaulting to combative against others with different stories to tell.
