when i was a kid i would wake up seeing a geometric pattern like this on the wall:
i could at will zoom in or zoom out the wall which made me think i had powers for i had not heard of television
later i would think of an stereogram effect but theres much much more to it
if you stare at it for a while you may notice a swithc in perception, lateral sight increases and depth perception augments
i can control it at will now thanks to my high control of eye convergence so i know why staring at that gives you a stoned effect
you just tend while looking at that to see it double but your brain conpensates and overimposes the images your eyes see double
i can do that at will i can converge my eyes while looking at that and i can tell how my brain corrects overimposing images which changes perception
i think we use our sight wrong, as a matter of fact i think we are in an animalized state due to a damped perception, we have a dual cpu witha single chip operating system
