So one interesting thing I find myself doing if I'm not taking my ADHD meds on a given day, is day dreaming way more. I tend to lose focus and run around in my own mind even if I'm doing something that's __supposed__ to be stimulating! (ex, using my phone) I don't know if that's a good thing to be fair... it hasn't ever felt helpful. I've had to rewind 20minutes in a movie because I realized I had created my own separate-but-parallel story in my own head that is only now just clashing with whatever plot point that is currently happening.
To me at least, it does feel like however optimized a thing is to take your attention, imagination is more attention-stealing.
