Mister Nightdog, being a child of the '60s much more so than myself (I was born in 1958), tried quite a few of the mind-altering substances that were available in a university town and says today that he liked/enjoyed at least a couple of them. He was particularly amazed by the lysergic acid diethylamide, and how it seemed to present the inter-connect-ed-ness of all things.

I will also say that Levoquin, which I took for a short time during chemo, has the potential to produce some VERY INTERESTING dreams. :D
