I kind of thought it was like talking to your Sub-conscious or Super Ego.
Your super-ego is your apparent self, the You that you put forth for the world to see.
The Ego is the True Self.
The Id is the Primal Self. Dog would probably be a good example of the Id.
To see "Your Brain" throw a hissy fit over all the horrible places you delve into makes absolutely zero sense, since the brain is the physical being of the mind, and the mind is what made the decision to go there to begin with. The body does not consciously move on its own.
