For me it’s time signatures in music. I grew up playing instruments, played in several orchestras, etc. But no matter how many times someone tries to explain time signatures to me, it makes no sense. I don’t understand why people place such importance on it. To me, notes have a pitch and a duration, maybe some dynamics. That’s it. I don’t understand why people try to needlessly complicate it. It doesn’t give you anything.
My wife will hear a song and go “Oh neat, it’s in 5/8.” And I’m like “How tf do you know that, and why does it matter?”
Add in a psychedelic experience or two, and it becomes impossible not to recognize how ridiculous it all is.
Can be done without them, of course, but psychedelics can blast you right to that position, for better or worse.
I’ve taken the slow route and have been doing mindfulness meditation for a decade which probably plays a role in all this.
