In this episode of Hysterical, I explore the eerie case of the Halifax Slasher, a wave of fear that swept through a Yorkshire town in 1938. It started with a few alarming reports of a man attacking women with a razor. As newspapers caught wind of the story, panic spread like wildfire. Vigilante groups formed, suspects were hunted, and the town spiraled into chaos. But what really happened in Halifax—and why does it still stand as a textbook case of mass hysteria?

In this episode of Hysterical, we explore the June Bug Epidemic of 1962, where a seemingly innocuous event turned into a widespread phenomenon of mass psychogenic illness at a textile factory in Strongsville. It all began when a worker reported a mysterious bug bite that no one could find, leading to similar reports across the factory floor. As more workers experienced the same symptoms—unexplained bites, nausea, dizziness, and rashes—the panic spread, even though no insects could be found. This episode dives into how the epidemic escalated, fueled by stress, social connections, and the power of suggestion, ultimately revealing how deeply the mind can influence the body in collective experiences of fear and anxiety.

In this episode of Hysterical, we dive into the bizarre Tanganyika Laughter Epidemic of 1962, where a simple giggle in a classroom quickly escalated into an uncontrollable outbreak affecting over a thousand people across East Africa. It all started when three schoolgirls at the Mission Girls' School in Kashasha village began laughing uncontrollably, and their laughter spread like wildfire, eventually affecting both children and adults in neighboring villages. Symptoms ranged from uncontrollable laughter to crying, fainting, and exhaustion, leaving medical professionals puzzled as no physical cause could be found. As the epidemic unfolded, we explore the social and cultural tensions in post-colonial Tanganyika, where the collision of traditional African beliefs with Western education may have contributed to the phenomenon. This episode examines the intersection of mental states, social connections, and physical health, revealing how a seemingly simple act of laughter became a powerful expression of collective psychological experience.
