From Brian Greene's book "The Hidden Reality"
"The strangest of all parallel universe proposals is one that emerged gradually over 30 years of theoretical studies on the quantum properties of black holes. The work culminated in the last decade, and it suggests, remarkably, that all we experience is nothing but a holographic projection of processes taking place on some distance surface that surrounds us. You can pinch yourself, and what you feel will be real, but it mirrors a parallel process taking place in a different, distant reality"

"If this line of reasoning is correct, then there are physical processes taking place on some distant surface that, much as a puppeteer pulls strings, are fully linked to processes taking place in my fingers, arms, and brain as I type these words at my desk. Our experiences here would form the most interlocked of parallel worlds. Phenomena in the two -I'll call them Holographic Parallel Universes- would be so fully joined that their respective evolutions would be as connected as me and my shadow."

This is from one of my favorite YouTube channels:
The author of the video -who is a physics expert- seems real button lipped when I ask him about this, but someone discovered an uncanny resemblance between his ideas and Hermeticism:
When I saw this the first time it was like a bomb went off in my head.
