Interesting - while I can make myself do the ‘silent talking’ thing, my normal internal monologue is usually disconnected from my movements basically completely. It’s pretty normal for me to be thinking ahead or of other things to say while speaking at the same time. I do some music gigs here and there, and if I know a song well enough, I find my mind drifting and monologuing on random observations about the venue, or people around me, or even something completely random, while also singing the normal words to the song and playing guitar! I’m not sure who is more “normal”, or if there even is a “normal” here!
