i have always had some difficulty articulating my inner world to those who have more fixed frames of reference. as an extrovert, i have a comfortable and fluid connection to the outside world; the greater my exposure to it, the richer my inner world becomes. judgments and memories and ideas, distinct entities, are layered with Meaning.
some would call this inner judgment (Fi) combined with inner imagery (Si) blending to create a shifting inner landscape. but i have noticed that this shifting landscape makes some people uncomfortable (for it is the seat of certain constructs that others would prefer fixed, values for example). i have also noticed that i have difficulty articulating it and am best able to do so when i stop and direct my focus on one point. like a globe spinning on its axis, and stopped with my fingertip, i am able to lift it and describe precisely what i see at that moment.
but this description would be for the purposes of externalization for someone else's benefit. i rarely see the need to externalize my inner world, as a) i can fall into a kind of contemplative ecstasy the more i ponder that landscape (what @Victor calls high response but in my case the stimulae is this inner landscape of external-flavored Meaning), and b) describing it is painful. at least, very difficult to do so as one would feel asked to describe a cosmos in but a paragraph.
mine is another type of thinking, one that is not limited to what the physical senses reveal to me about the physical world. it starts in the outer world, which is limitless, and continues on to join some inner constellation of thought construction and something else i can't define. but it is as boundless as the external world.
a poet shapes his inner world into external form. i do just the opposite.
