I spend a lot of my time writing, and when I'm ready, stuff just pours out. I'm always thinking the words as I write them, but there's not lots of intervening internal dialog.
Often it's like I have no clue what I'm going to write, until I write it.
But maybe that's just that I've trained myself to write my internal dialog down, instead of just thinking it. And when I'm stuck, I definitely talk to myself more. Sometimes to the point that I can't write anything.
When I'm really focused on something, on the other hand, it's very hard to stop. I'll be so tired that I can barely think, and yet I can't clean my teeth and wash my face without scribbling notes on scraps of paper. Which, by the way, I dispose of securely ;)
Also, it's obvious that there's a lot going on that I'm not at all conscious of. I can stew over stuff for days, or even weeks. And then, out of nowhere, it's there to be written. Or done, as the case may be.
