Do you think conversations in your head?

Do you think conversations in your head? I'm wondering do you guys imagine/plan/analyse/think conversations in your head? I'm realising that I do this all the time, sometimes the conversations are about near future things such as rehearsing conversations about what I need to say at like a pizza shop while I'm driving to that place but it can also be about conversations that are way too far from now. I sometimes even fantasise about myself talking fluently at a place where I wanna be fluent. It's so funny for me sometimes but this too much planning and preparation in my head takes up energy other times. Does anyone else do the same or something similar?
