i've only had an auditory hallucination from weed once, i was in my friend's shed in his backyard smoking with him, and i heard my mom yell my name, i thought oh shit! i'm fucked! and started putting away my lighter and my piece and stuff, then i got up and opened the door, looking around in the alley.

my friends asked me what i was doing and i was like "didn't any of you hear that?! my mom yelled at me, how'd she find out where i was?! i called in sick to work today!"

they all just busted out laughing.

that's the only time it's ever happened. I do however get intense auditory hallucinations when i trip on 2c-i
