I was so happy that cell phones came into existence. I can now have those "conversations" with my stearing wheel and people think I am simply on my cell. I talk, react, go through answers and flail my hands/arms. And I am perfectly normal. Just feel really funny when the grandkids ask me "grandma, who are you talking to?" I simply say "myself" and they just dismiss it.
i think it's normal to have this my mind races all the time my therapist shared the same experience with me :)
