Time travel claims and urban legends are stories that people share about things that have happened to them or things they know about that involve time travel. It's usually stories that seem impossible, like someone suddenly appearing out of nowhere in a place and time they weren't supposed to be, or about a mythical machine or creature that can move people through time. People usually tell these stories because they're exciting and mysterious, but unfortunately some of them aren't true. It's important to remember that just because someone tells a story, it doesn't necessarily mean that it happened.
