My first roll wasn't very intense, a stimulated heightened mood feeling and musically-induced euphoria.
It was all very enjoyable of course but the best kind of rolls are the ones when everything takes on an under-water feel, then your eyes twitch so rapidly you get double vision. Then you go for a walk outside on a nice clear day, look up and feel overwhelmed by the sky. When you're amazed and amused by everything and you feel like a god.

Only then can you say that you've lived.
