Now that we have read a number of these vampire novels, I am starting to gain a further grasp on what a vampire actually is. From the get go, I found that vampires have a a need for interaction (often with humans). This strikes me as interesting because in most situations in the novels we've read, the vampire starts an actual relationship with it's prey. This is no different in Dracula... This proves that not only do vampires have a thirst for blood, but they also have a thirst for connection. Thus proving their humanity, albeit a small amount at times.
Dracula also gives way to the idea that vampires don't eat. This contradicts what i just said about vampires having humanistic tendencies...humans need food and water to survive. Authors display the vampire's uniqueness from humans in that they do not (need food and water to survive). They do have a need though, blood. This can be seen as their "food" however, and that would give even more value to the fact that they DO in fact have aat least a shred of humanity.
Also common among the vampires we've read about and Dracula, is their (seemingly) charming personality. In every account of a vampire, the human prey has noted how engaging and interesting their vampire is. I believe that this is also meant to show their human side. Dracula shows this in how refined he seems.
