Vampires are people with sharp teeth, maybe from this idea has developed the idea of vampires. It`s true the americans believe that Vlad Tepes was a vampire but the only connection could be the fact that he killed all of those who were doing bad things like stealing, lying etc. Nowadays the concept of aliens or vampires is more common. People are not afraid anymore because there are so many movies right now, that the main concept has soften over the years. Vampires are in the same time humans and so they have also a good side. Every story has a sad part, a romantic part and a scary part. That`s why film has action combined with drama, and thriller scenes.
We can`t talk about something we don`t believe in. Maybe there are somewhere vampires, like there have been so many proofs of alien existence during the years. We are just not sure and this it`s quite scary. Do vampires feel extreme sadness or they don`t? it`s a difficult question. From their description, no, they are senseless creatures that don`t care about anything but blood. But some movies have chosen to have love stories in vampire movies. It just gives them a more real look. So, if we want to believe in movies and in the idea that there is no smoke without a fire, then we are free to believe in vampires and in their ability to fall in love and become sad. In the end, what really matters is us. Believing in things like this is not out of the ordinary so maybe everything that we heard and we see has a certain impact on us. Vampires are just like aliens we need facts to make us realize that they really exist.
