I’m exactly the same way other than the last part. For me, it’s a relief to switch my brain to something I know I can’t solve and get lost in the never ending depths of “what if’s”
Oddly, that is the exact reason I enjoy quite a bit of techno or electronic music while I'm trying to work. My brain pretty much knows what's coming next with the repetitive beats so I can actually focus on what I'm doing.
You allow yourself to run wild for relief where as I rein it in... hard... in the opposite direction. This extends so deeply that I normally watch the same movie, for months on end, every night to fall asleep. Last several weeks its been Ad Astra. Quiet, dark, slower paced. It's Apocalypse Now in space with no war.
Anyhow... This has been a fascinating and radically off-topic exploration into my INGO 1/2 twin.
