Yes, there are real vampyres in this world. True ones that were around long before all these Twilight crazed teenagers declared themselves to be vampires. Don't get me wrong, I like the books but there has been an enormous influx of fang-wearing teeny-boppers since the publishing of the series.
A lot of vampires are hiding because they are scared what people would think of them, also due to the fact that holly wood makes them look bad. With the internet it is become a safe haven and also with the source of information that the internet has to offer.
