from my experience acid doesnt make hallucinations from nothing. simply allows you to focus on tiny details unnoticed sober. this video is scary as fuck. sober or not. but in no way is that acid imo. edit: lsd is alot more mental alterations than visual imo.
In my experience with hallucinaginics it is more like your imagination at work, more to do with what is inside your head then anything.
i dont quite agree with that ive actually had visuals like this video while looking in the mirror granted they werent as spectacular as when his face changes into like a zombie thing and shit but i saw my face melting and shit and i only had three hits so i def imagine that if someone had taken like 5+ hits then they would def have visuals like this and im sure the purity of the acid would help with how it effects you too
