Crackpots

I find that there are generally too few crackpots in medieval fantasy worlds, compared to what ratio one would expect in a world with large numbers of diseases, death, magic, and lack of mental health hospitals. Don't you agree?

How many times have you read a description of some town in a module or setting and they talk about the "one guy" who is crazy. There should be more than one guy. There should be quite a few crazy-ass mo-fo's running around causing mischief, I think. And it should be hard for the PCs to tell the difference between the actually crazy and the eccentric. Maybe that treasure map is just a doodle made during one late night love affair with the Absinthe or magic mushrooms or whatever.

There should be more mind-altering episodes in these settings, shouldn't there?

Just a thought. I am feeling a bit crazy today myself.
