I do believe in vampires, werewolves, and other mythical creatures, but are they real? No. According to the sub-culture, they are real. The Sub-culture of vampires... is where people act like vampires. They drink blood and they dress in a very dark fashion. I went to Ripley's Believe Or Not Museum in Myrtle Beach, South Carolina, and I learned that back then there was a Prince who drank thieves' blood. Was he a real vampire? Maybe. He might have had some psychological problems though. I know that werewolves aren't real though, because you would not be able to survive the whole transformation of forming into a huge beast.
Vampires are not real. They are mythological beings who survive by feeding on the life essence of other living creatures. There has been a lot of interest on these creatures that they are sometimes thought to be real.
Consider this. According to a science, if you start with the amount of blood that a tiny vampire BAT has to drink per night and converted that to something the size of an adult human, the human vampire would have to drink at least a bathtub full of blood each night. How romantic is that?
