This whole thread has stopped me in my tracks-- 4 or 5 years ago I had a very powerful experience where I found myself seeing/floating in a grid...it was a strong realization, and it strangely reminded me of the holodeck on Star Trek the Next Generation, if anyone's seen that. I clearly saw it as a grid, but until now this is the first I've heard others speak of the same thing! Very amazing...I guess even though the universe is subjective, our perceptions often have strong similarities...!
