"There are such beings as vampires, some of us have evidence that they exist. Even had we not the proof of our own unhappy experience, the teachings and the records of the past give proof enough for sane peoples"

This quote by Bram Stoker suggests that vampires are real and that there is proof to support this. He states that there is proof of their existence from both personal experience and from the trainings as well as records of the past. He suggests that those that are rational must be able to approve this evidence as well as rely on the existence of vampires. This quote suggests that vampires are not just a myth or a legend, but that they are genuine and have actually been around for a very long time. It also indicates that those who are unbiased as well as happy to approve the evidence needs to be able to believe in the existence of vampires.
