I only got REALLY paranoid one time. It was Canada day and me and 2 friends were stoned out of our minds in a tent in the woods, and fireworks were going off. I thought it was guns, I was terrified, then they told me they were fireworks. Thats my only paranoid story..hehe
i don't think i've ever gotten severely paranoid although, i suppose in that sense, one time i was just really high and we were eating general tso's chicken and they told me it was chicken fetuses yeah, no good, probably the most gullable time in my life
