I took some bad acid in November of 1965, and the after effect left me crazy and helpless for six months. My mind would drift into a place that was very electrical and crackly, filled with harsh, abrasive, low grade, cartoony, tawdry carnival visions. There was a nightmarish mechanical aspect to everyday life. My ego was so shattered, so fragmented that it didn't get in the way during what was the most unself-conscious period of my life. I was kind of on automatic pilot and was still constantly drawing. Most of my popular characters—Mr. Natural, Flaky Foont, Angelfood McSpade, Eggs Ackley, The Snoid, The Vulture Demonesses, Av' n' Gar, Shuman the Human, the Truckin' guys, Devil Girl—all suddenly appeared in the drawings in my sketchbook in this period, early 1966. Amazing! I was relieved when it was finally over, but I also immediately missed the egoless state of that strange interlude. LSD put me somewhere else. I wasn't sure where. All I know is, it was a strange place. Psychedelic drugs broke me out of my social programming. It was a good thing for me, traumatic though, and I may have been permanently damaged by the whole thing, I'm not sure. I see LSD as a positive, important life experience for me, but I certainly wouldn't recommend it to anyone else.
