The Dancing Plague

Back in the 16th Century a woman began to dance - but couldn't stop. Others began to join her and a plague was declared and according to some reports, 15 people a day died of exhaustion. As weird as it seems it's not an isolated case, over the years similar phenomena have been observed. What causes this? What does it tell us about human behaviour? Is there anything that it might tell us about cultic groups? Plus a little spooky Tweet of the Week. Why not become a patron for just £1 per month? https://www.patreon.com/whatshouldithinkabout
