Edit: Thinking on this more, I may not have had an internal monologue when I was younger. I recall when I was maybe 11 or 12, I had a sudden, distinct moment of increased self-awareness, after which my internal monologue became my predominant mode of thinking. My first thought was that all of my mental activity up till that time had been in a fog, and that I really hadn't even been a fully conscious being. I crossed some kind of cognitive rubicon which my previous self couldn't even understand. I assumed this was a normal phase of mental development at the time, but now I'm curious if others have had similar experiences.
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.

Often I can feel that I have a complex idea more or less nailed down, but it's an effort to stop and put things into words, even internally.
Other times though even an internal monologue isn't enough to tease out the edge cases or weigh the tradeoffs, and I need to write stream-of-consciousness style.
Different styles of problems lend themselves to different approaches, I think
I've never had anyone else remember or experience this before and I think its important.
My story was that I was playing around in the garden. I was messing with a pile of stuff placed against the garden wall and as I'm touching something, suddenly I feel a huge electric shock. There was an old electric socket there, probably for pluggin a grass cutter. I remember the strong tinge around my whole body and how it pull me into it. I quickly twitched and jumped back. I remember telling myself "Wow, I could have died there". And, "electricity really gets you stuck" (I remember when I was that age adults would warn you about touching electric sockets, saying you could "get stuck to it", I guess not grounding installations was common).
Learned myself to read before getting to primary school.
Also can bypass verbal thought. Can internally hear and visualize mostly anything. Don't recall not being able to internally hear or visualize things.
