I get a feeling alot like that when I smoke Salvia. I don't know if its the same cuz i cant really describe it either but that sounds about the same, i smoke weed every day with a day off every so often and that gets me baked like everyone else, i can get really baked and it is the same as everyone else or normal where i can operate daily. but i got this salvia in toronto and ive smoked it three times and i felt totally fucked, just like you described all my friends were talking to me and i couldnt really hear them, they were just like colours and like slow mo talking, i guess its just a weird reaction some people have but i wonder what would cause it, there has to be something that triggers it.
i never was like this... it was always really chill... but the past few days its been kinda not too awsome. i think it has alot to do with stress... just chill... make sure your head is on good before you smoke... dont stress about anything.
