I dreamed that I had found a website that looked at first as thought it was the usual unpleasant sexual tourism thing, guys visiting impoverished countries to do nasty things. But it was worse. It was a cannibalism tourist site, where you could arrange to visit places so benighted that they'd sell you their children and you could eat them.
The site was disguised as a kind of crackpot medical clinic called the California Creative Radiology Institute.
I think this is the first actual Internet nightmare I've had!
