I have a monologue in the form of an argument between different perspectives. I can envision things, but not clearly, so unclear that at first I wasn't sure if I could or not.

I also feel like I have access to a very limited range of active memory, and when I store old information it can be very hard to find. Like a slow and fragmented HDD on a new-ish computer.

For me it's a clear audible monolog which breaks into a dialog of self talk for problem solving and day-to-day planning. It sounds nothing like my physical voice but I feel that's my truest self

I've had this wonderful experience after learning sign language that for the first time I feel like I can talk to other people with the voice in my head! And when they sign back I hear a voice speaking aloud each sign. What I discovered is I'm quite a different person when I don't have to use my physical voice to talk, I'm much more expressive and fun, which I guess I find difficult to translate through the voice of a late 20s man. Something to work on!

Something I've wondered about is how noisy people find images: https://www.reddit.com/r/noisygifs/ is fun to explore. I find all repetitive motion has sound, like anything, no matter how abstract, I cannot help hearing some weird audio pattern when I look at it

That's interesting about sign language. I wonder if it helps with plasticity.

A lot of monologue, though sometimes I find the abstract part has raced ahead and finished the thought before the words have time to be thought. If I stop those words because the thought is complete, it feels weird.

Sometimes just visuals, especially when I’m trying to understand geometric problems.

Totally agree on that abstract bit going faster, sometimes it feels I'm verbalising thoughts for completeness!
