I get stoned like that a lot. The music I'm listening to or just the sounds around me, the scenery, wild conversations, faces that tell a whole story just by looking at you. It's why I almost never use drugs. Anything more with my perceptual chemistry might put me over the edge!
I hope you took turns driving, though!
It's nice to see that there are others like me (I felt such a weirdo).
I try to stay on alert when driving, thanks! :)
