Can't say I have experienced anything terribly close to that but I'm interesting in whether or not anyone else has. The one similarity I have experienced is the sensation of breaking through while laying on my back and being greeted by figures that are standing or kneeling near me and looking down with earnestly loving auras. Much like coming back here as reality and convention reassemble themselves and the transitioning adornments condense back into our Newtonian-bound laws and environmental constraints. I've had experiences [going] that are not unlike Rick or Morty coming out of Roy: A Life Well Lived, after completion of the game.
Have you written up any trip reports or gone back after your two breakthroughs? Would love to hear more.
