Vampires, Werewolves, Shapeshifters, Aren't Real But People Are Starting to Believe It!

I think that maybe we have been going overboard on all of the mythic movies. Don't get me wrong I personally love them but, some of the children I know are really starting to believe that these things are REAL! My friend has talked to her son until she is blue in the face and he is animate about the fact that super heroes really exist and so do vampires, werewolves and all the rest. I would love them to exist but I've never seen any have you? I guess when people or children won't accept reality over fiction maybe it's time to tone it back some.
