What are the psychedelic drugs about?

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.
