No, one hopefully, speaks more than they think. But for some people the thinking seems to happen aloud.
As if they are narrating their own lives. Describing in real time, their motivations as they attempt to bring them into being. When done with anchor of habit, these actions can occur with a flourish. Appearing as a well rehearsed dance, the story and the actions are indistinguishable. Without the habit, it is like looking at a child try to get an unruly dog to obey. The commands are spoken but neither the child or the dog can be said to be in charge.
