Constructing stories around the experience is how we reconcile it after the fact. I can't explain the DMT elves, but these forms could have an explanation as simple as poisonous mushrooms impairing the rate at which your brain samples sensory data and attempts to normalize and cohere it.
Merely watching videos of these patterns doesn't change self perception, so drugs probably do a lot of other stuff, but revealing the underlying structure of the universe seems less likely than these being equivalent of a guitar effects pedal on a signal.

That is some dope Original Research right there, lol
I thought I might be tripping actually when I saw that, I had just taken a psychedelic but there is no way enough time had passed for it to take effect.
