I certainly hope there is nothing with you, because I talk to myself a lot. Because of wondering if I am crazy. I have asked others if they do this. I got a surprising yes from many. I am just talking about talking to your self and not an imaginary friend. I also think it helps one to hear a certain thought aloud to see if it makes sense. In other words, what your judgement be if someone else uttered it. It seems to bring a certain amount of objectivity to it.
