E=mc2 could be a shower thought if you haven’t learned it before… Yes in the course of all of human history someone might have thought of it previously, and whoa to history if maybe they weren’t in a shower, but the white noise, and warmth of a shower can allow your brain to chew on things you may never encounter in the world, and indeed be born of a showering state of being, indeed I would be surprised if most shower thoughts hadn’t already been thoroughly documented by some scientist looking to be the next George Washington Carver. Shower thoughts do not have to be original, but they should at least shed light on things in a way you, and maybe most people, wouldn’t consider. Personally, I hadn’t considered why my brain does that since I at one point was diagnosed with general anxiety disorder(gad), and frankly every moment was terrifying, and my brain and myself were just stuck in a cycle of nightmare scenarios, and now that I’m past that, it makes sense why sometimes I remember cringe scenarios and it isn’t gad starting to take hold again.
