Do you talk to yourself?

Recently I find myself talking to myself and it is happening with alarming frequency.

I realized in high school that I am a very auditory person - I think in trains of thought that are the constant banter of several  inner monologs all competing for my attention. These inner monologs are spilling over into the spoken realm and because I am so used to hearing them in my mind, when I hear them through my ears I am not sure how long I have been muttering to myself. Scary.

I won't get any further into how my thinking works here, but ask you: how do you think?
