@animatrix1122: When millions of spiders suddenly rained down from the sky, terrified residents witnessed a nightmare straight out of a horror movie. But this strange event wasn’t magic — it was nature! In rare weather conditions, spiders use a phenomenon called “ballooning”, releasing silk threads that catch the wind and carry them through the air like tiny parachutes. When they land, it can look like a spider storm covering everything in silky webs.
