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
Hey same!
My thoughts are a constant flood of characters or quips in different voices and tones.
DM ing for me was work but also a true flow state because it gave all this general chaos individual purpose. I’d like to think it lead to good sessions!
And when long running or important characters would eventually meet in game, I’d sometimes get carried away having conversations in multiple characters with myself. One time it went on for several minutes before the table just started laughing.
