All the damn time. Probably too much. But there is, among a multitude of thinkers, a separation between the meaning of words and the act of speaking them out loud. Lacan for instance: https://nosubject.com/index.php?title=Enunciation
An example is if you are trying to work something out, or understand something I think if you can't clearly put it into words what exactly you are trying to dissect then you really don't understand it at all. This exists under the purview of speaking / enunciation as thought, and mental imagery does not strictly follow a lineage of stages like an argument, or even a linguistic frame for that matter.
My favorite times when I talk to myself is when I'm drunk because it feels like someone else is talking and I'm just on a ride. Probably self absorbed because I like to hear myself talk if I'm being honest.
It helps me organize my thoughts and prioritize. Also I do this thing where ill ask myself a question that I can reasonably believe someone would ask me (or would just like to talk to someone about) and then just answer the question. It helps me "teach" so to speak so I know where I'm not really as well versed in something than I would like.
As an example I was out foraging for mushies and since I knew the next day I'd show a friend where I'd find chanterelles I began reciting to myself to differences between them and false chanterelles etc. It made the actual exchange a lot smoother and it helps with my social anxiety
Me too, I like rehearsing conversations I might have. I do it A LOT, loudly. And then even if they don't happen I still get to share my thoughts (albeit with myself lol)
Sometimes I pretend I'm speaking with aliens that somehow know English but nothing else and go into stupidly deconstructive rants about aspects of our culture. Honestly its kinda fun and helps you step outside yourself for a bit
I dont usually talk aloud, but I do feel like my life is one long, unbroken monologue. I even find myself explaining things that I already know to literally nobody
i think it just comes down to how ur brain is wired. Like how some people's thoughts they actually hear out loud like someone is talking on the inside of their head and other people don't hear their own thoughts, some people might process thoughts better if they actually speak them out loud like operating the part of ur brain that handles speech limbers up the parts that handle ur internal monologue. IIRC you can probably fix this, I used to do it too & stopped myself & dont talk to myself at all anymore
I don't really talk to myself out loud, probably because at this point in my life I am very rarely at home by myself, but whenever I am alone in a room or something like that, I find myself kind of silently mouthing the words of a conversation with myself. Usually there are like two "voices" talking to each other about whatever I'm thinking about, so it's more of an internal dialogue than an internal monologue. It's a weird but I guess pretty effective way to think things through. Often I don't even realize I'm doing it, it's sort of instinctual. After typing this out I realize how weird that sounds. I wonder if this is a thing that many other people do
Honestly having read a lot of the theory behind structural dissociation, I think plurality is something really beautiful and remarkable. It's amazing how the human brain can adapt to cope with the most extreme circumstances of abuse. For many people who are plural, it's not a malfunction, it's a saving grace.
