During downtimes, I've had this non-stop first-person narration going through my head for a long while now. When I'm deep in a project, it is often narrated by my character. I think his/her thoughts in his/her voice. I work out dialogue for scenes that I will soon write or revise. I come up with scene openers and whatnot.
Right now, though, it's just me in here. And I am irritating! I'm on this list kick. It's stupid and mostly nonsensical. I will think a thought and then try to start a list about it. Basically, I mention the type of list it would be, but it goes no further. It always trails off all dot, dot, dot. (But not in a MAMMA MIA movie dot, dot, dot way.)
For example:
I am bored.
Immediately, my brain will rephrase it: On the list of people who are bored . . .
That smells bad = On the list of things that smell bad . . .
Dwayne is tired of soup = On the list of people who are tired of soup . . .
You get the idea here. It's completely obnoxious.
On the list of things that are obnoxious . . .
Make. It. Stop.
