Understanding Collective Hysteria and Mass Psychogenic Disorders

TLDR Collective hysteria, also known as mass psychogenic disorder, is a phenomenon where groups of people experience physical symptoms without a clear medical cause, often influenced by media, placebo effects, and the power of suggestion.
