@Alonzo I sometimes have an internal dialogue, sometimes not. It really depends on what I'm doing. If I want a coffee as described, I see the coffee as an image in my mind or as the experience of drinking coffee, and then just do it. Actually, I might already be doing something before the thought even fully forms in my head ... Which I suppose is analogous with Se and not thinking things through, but really, when I want to do something, for example pick something up, I'm already doing it before I've even consciously registered it as "I am going to pick this up now". Not that others have that sort of internal dialogue, but usually, my decisions are made in my brain before I've even... decided to make a decision? Lol.
The only times I actually have an internal dialogue, I'm not actually talking to my own self. I'm imagining responding to a post on a forum, or arguing with another person in my head. I need to have a discussion with someone that's not me, for me to flesh out my thoughts into actual words. Even in my thoughts, I need to extrovert them and bounce them off something else. (Like how I'm responding so much now, after writing a one-liner, because I have a prompt now, and beforehand the prompt was somewhat lacking.) When making an actual important decision, I feel like something is missing if I just try to decide in my head, and I need to write it down or talk to someone in order to actually be able to see it in the world and make sense of it as something that has an actual impact as opposed to the amorphous nonexistence of thoughts.
