No, the 3 is about the external face and the internal face...and is based upon a particular way of reacting to inner shame as a driver.
But being very internally focussed - do you naturally reach for metaphors and pictures and imagery in your thought world? Or do you mean more that you imagine real world events or experiences?
Hmm, how to explain what goes on in my head...
Well, by internally-focused, I mean that I have the tendency to be very oblivious to my environment, almost like I'm on "autopilot." I'm very shut out from other people and my surroundings, and being approached by someone when I'm in this state is incredibly disorienting to me, like someone waking you up from REM sleep.
As to what exactly I'm thinking about when I'm in my head... usually about real world events. What's going on, what I need to do, current events relevant to my life in some way, how I feel about what's happening around me if I'm observing it, inner commentary/monologue. No pictures or imagery unless I'm daydreaming (which is a conscious choice when I do it and not the focus). Metaphors, nope. I'm very straightforward, clear, and concrete in my head.
To think up some kind of example... let's say I'm walking from the parking lot to my classroom at school, and I'm in my head thinking about, say, where I want to get food on the way home or something. I'm walking on autopilot, using my memory map--I don't have any sort of conscious awareness of anything going on around me unless it's
very different form how it usually is (like, say a tent is set up in the field of something, when usually it is empty). Let's say a hypothetical person approaches me, says "excuse me" or something like that to get my attention. I feel jolted out of my mind, and my initial reaction internally is something between 'god what does this person want leave me alone let me go back to what I was doing' and a sort of observational 'this is a dude, he's wearing this shirt, blah blah, he just said excuse me, his eyes look kind of wide, I think he's worried about something, oh no does he want me to do something, oh god I don't want to, I need to go to class, oh no oh no what do I do'
And these thoughts happen in like, 1-2 seconds. Not necessarily always in words, either, but mostly in feelings, with maybe a few word associated/going along with that. And it is my constant state of mind/narration. If the guy follows up with "Do you know where the student union is?", my next internal reaction (again over the course of the next 1-2 seconds and in some strange land between feeling and verbal thought) might be something like 'Oh good, he doesn't want me to do anything, it's a simple question, I know the answer, now I can tell him and go away' or something.
And afterwards, on my walk to class, I'd be processing and replaying the event that had just occurred in my mind, analyzing it and making sense of it and how I think/feel about it.
So when I say I am internally-focused, I mean that while I'm distant from my environment mentally, I'm also very grounded in the present and worldly experiences.
