When people say there is another you in the world is that true?

The German Word Doppelgänger (literally "double-goer") is used for the "double" of each person that is said to exist, kind of like your "evil twin." There is a superstition that it is a sign of bad luck if you should catch sight of your double. There is no truth to this bit of folklore, but it has a certain weird ring of truth to it, so I wouldn't want to say that absolutely, because I like weird phenomena. I think that genetically there are just so many physical types in the world, and often one does run into or hear of someone who looks very much like oneself. I always get a kind of shiver if someone tells me they know someone who looks just like me, and this has happened several times. I tell them, "Don't tell me about it, I don't want to know my Doppelgänger!" I don't really believe in it, but I like the idea because it's weird, like the idea of parallel worlds (which actually I think is true).
