For me there’s two separate participants, a ‘talker’ and a ‘listener’. My mind identifies more with the talker, because that’s the one that has agency. Since there are two participants, both of which are me, I talk in 1st person plural (‘we’ve got to do …’, 'we thought about this earlier’). I stopped being afraid of being alone after I started having an internal dialogue around the age of 11, since having a second participant in the conversation meant I was always in company.
Edit: Wow, looks like there’s a lot more diversity in this than I was expecting
No monologue for me. Just image and sound. For example, when thinking about a situation, I’ll just imagine it as a moving picture, but there’s no internal narration to it. I don’t think in sentences. I just think about the image or feeling and then process it somehow.
I’ve discussed this topic with others before, and they don’t really get it lol. Well it’s equally weird for me to think about it their way, constantly having an internal monologue.
I don’t get sound or image (pretty bad aphantasia), but i do have a monologue. Can you believe there are people out there who have NOTHING going on up stairs? Yup, people who have no pictures, no sounds, no monologue, no anything.
Same for me, I can see, hear, feel and even smell memories or fictional situations. For other people this is not possible, they do it differently.
