Dance epidemics are unusual events where groups of people suddenly begin to dance uncontrollably, often in public spaces. These phenomena can last for hours or even days, with participants unable to stop dancing despite exhaustion or injury. One of the most famous examples is the Dancing Plague of 1518 in Strasbourg, where hundreds of people danced for days without rest. The causes of dance epidemics remain unclear, but theories suggest they may be linked to psychological factors, social pressures, or even mass hysteria. Some researchers believe that these events could be a response to stress or trauma, allowing individuals to express emotions through dance in a communal setting.
