Nah bro, im not exaggerating them. Dunno.. you might be thinking about it in a more intense way then i am, but to me it didn't seem too crazy for weed. Ive never gotten that high before either, i usually just got some small visuals and auditory hallucinations like you said you do. I never got anything close to as crazy as that. And i understand what you mean by seeing patterns of faces in shit too, because i get that sometimes when i smoke alot also lol. Ill just be looking outside the window at the leaves on this tree, and ill just start to see them forming eyes. I always end up closing my blinds because i get so paranoid.... Good times.
BTW i used a waterfall bong, it gets me way higher then the pipe i have with less weed. 2 bowls from my waterfall would be like 4 from my little metal bowl.
