you're right I believe dungeon's and dragons has a werewolf/vampire hybrid too.
But according to historical sources like historical mythology in various cultures has there been any werewolf/vampire sightings. I know that there
are lots of cases of werebeasts.
But werebeast vampires. sorta defeats the purpose. Don't get me wrong I wish the movie Underworld was true. Personally we could use more hot
chicks running around it skin tight latex catsuits, especially since the michelle phiffer catwoman is now out of style. Shame too.
Hell I'll even settle for women running around pretending they are vampires if they keep the catsuits.
but what are the OP's reasons for believing in werewolf/vampire sightings. Other than wishful thinking.
It's possible if vampires did exist. did being the operative word that they could masquerade as werebeasts. Some tales talk of vampires changing
shape into cats, bats lizards and mist. but werewolves?
