Mushroom behind 'tiny people' hallucinations identified phys.org

People on different continents, with no contact and no shared folklore, have reported the same thing after eating a particular mushroom: crowds of tiny humans going about their business in the room. Researchers have now pinned these Lilliputian hallucinations to a specific fungus rather than to cultural suggestion, which means the little people are coming from chemistry, not from stories.
