Shit, only two hallucinogens I ever did were LSD and shrooms. Bad Trip, chased by a fire breathing dragon (sparking wheel toy) up several flights of stairs (in a single floor building) into a room full of skeletons (people wearing adidas while dancing), where I drowned in the music waves before puking out my internal organs.

Last rave I ever went to, and it was years before I could look at tile grout without slipping back into hallucinations because of the depth perception.

Stick to the occasional beer and lots of coffee these days.
