I dropped an acid once and it was so strong that after 40 minutes the neck of my guitar was bending and the strings made visual waves when i strumed them. after 1 hour the guy i dropped it with was vomiting in my garden (after me watching him turning into an ancient totem pole which rolled a 5 foot tongue across my kitchen carpet, after 2 hours i was in hospital. after 3 hours i was in a wheelchair having completely lost the use of my body and my sensory organs, suspended in blackness for 2 hours watching huge golden spheres rolling towards me. I thought i had died.
I came to after midnight with my a doctor doing cramp exercises on my hands and everyone was there looking worried as fuck.
When i finally got home, my girlfriend at the time told me what date it was. I laughed and did a dance in the street.
The moral of this story ? Dont take drugs (on friday 13th)
