Some of these esoteric states are really weird, and it seems crazy to me that we are only now investigating them. This isn’t just “energy” woo that can’t be measured, there are clear physical phenomena.

Another good one is Niroda Samapatti (cessation) where advanced meditators can momentarily cease awareness https://awakeningdharma.org/havard-study-on-nirodha-samapatt...

Made me think of "How to do the jhanas" by Nadia Asparouhova: https://nadia.xyz/jhanas Cessation is impressive and the rest too.
