RE: TIL about the weird Dancing Plague of 1518

The Middle Ages and further back often appear to be very difficult periods of time. I’d like to think that among the people afflicted with dancing that there were some who were enjoying themselves, like a contagious concert of delights. The LSD thing makes the most sense but I find it hard to believe the effects would be constant instead of chronic since I’ve heard people having flashbacks but not something ever experiencing something constant. Maybe mass hysteria isn’t implausible either after the way the world’s behaved these last couple years.
