RS, described as the experience of being able to transcend one's physical confines and visit alternate, mostly fictional, universes, is discussed by many on Internet platforms.... The experience of shifting is reportedly facilitated by specific induction methods involving relaxation, concentration of attention, and autosuggestion. Some practitioners report a strong sense of presence in their desired realities, reified by some who believe in the concrete reality of the alternate world they shift to.

Obviously these worlds aren't real, but it's interesting that there is a cultural trend of more intensive imagination. It's anyone's guess if this is a dead end, or if it's leading somewhere.

Related: a smart blog post from 2017, Reality has a surprising amount of detail. The same thing struck me after playing on the Oculus and then taking the garbage out. In VR, there's a limit to how deep you can zoom before you get to one pixel. In reality -- and you could even use this as a definition of reality -- no matter how deep you zoom, there's always more. That's why physicists will never find a final particle or a grand unifying theory.
