Funny you say this cause I was just getting my eyes checked up and they said, if you look at something for a while like computer and look away it will be blurry for a bit it's normal and will go away. If it last then go see a eye doctor
i blacked out playing the beatles rockband they have all this trippy background shit and i was really high and played too long and just kinda blacked out for like 15 seconds haha
Unrelated, but when I would landscape over the summer, after getting off my tractor after 10 straight hours of mowing, things would meld into eachother and just like go all wacky and shit. So nuts.
