I personally don't really believe in this , but what if you met your doppelganger ,what will you do ? , Ive heard that legend has it that if you come face to face with your doppelganger, it's an omen or warning of death, for both you and your twin. Because of this, if you see a replica of yourself, run for your life. If you keep seeing your doppelganger, chances are that your days are numbered, because you'll soon see your demise. I'll freak out for sure , but of course im not sure .
