i've had two bad trips where i freaked out and pretty much irritated the people around me.
one time was on two hits of acid, the other time on an eighth of shrooms. i really don't know what happened, i've tripped plenty of times on the same amount and more sometimes and been fine...
the time on acid i thought i had died, or that someone had slipped me some other type of drug and i was going to be raped...then i started to forget who i was, i thought i had just woken up in a mental hospital and was seeing the reality of my life for the first time. that was seriously scary. i just kept repeating "who am i?" "am i dead?" "i died, why won't you tell me what happened?"
the other time on shrooms it was like everyone turned into demons and when they tried to touch me my skin felt like it was on fire. then i started thinking i had eaten a bad batch of shrooms and that i was going to die. it got to the point where i was asking the people around me for a pad of paper so i could write my family a letter telling them what had happened and how sorry i was. i don't think my friends were pleased.
like i said, i can't explain why those two times happened to be so scary for me, or why i felt that way when all other times i've had a blast or had serious spiritual experiences. ( is it normal to have those thoughts?? like about dying and forgetting who you are??) but the main reason why i would classify those as bad trips was bc i couldn't stop myself from saying whatever came into my head...i had no filter, and it was scary not being able to control your thoughts like that, especially when your thoughts are about dying or being killed
if i had to compare those particular times to something, i'd have to say it was like a salvia trip that lasted for hours...(salvia is scary shit)
i guess all i can say is i am truly awed by the power of psychedelics
