A doppelganger is defined as an appiration or a double of a living person, some one who looks just like you. There are tons of cases where peopel ask if they have seen someone before, or mistake them for "someone else" ...be honest, you've done it yourself... but what if you have seen them before? what if you have seen that same exact person somewhere, but what if it wasn't them? What if it were something else?
