i have really low tolerance (wierd, i don't know if it's genetic or something...) and i've had pretty mild visuals close-and-open eyed. what happens a lot though, is i'll think somethings something else for a while, like thinking a pile of clothes is my cat, or sometimes at night i'll be going to the basement to play videogames and the vacuum will scare the shit out of me cause i think it's my mom...
