Urban legends are modern folklore stories that often contain elements of mystery, horror, or humor. They are typically passed down through word of mouth, social media, or online forums, and often involve bizarre or shocking events. These tales can vary by region and culture, reflecting local beliefs and fears. Common themes include ghosts, monsters, and mysterious disappearances. Many urban legends are based on real events but become exaggerated or distorted over time. They often serve as cautionary tales, warning people about potential dangers or societal issues. Examples include the killer in the backseat and the toothbrush killer, which highlight fears related to safety and trust.
