Vampire

A friend of mine told me about the Origins of how vampires came from. It started off as that vampires were people with rabies, you know people bit by animals that have rabies. These people with rabies foam their mouth, act animal-like into terms of bite other animals or humans in the neck, sucking blood from two holes created by their fangs. Like to live in darkness because they either developed a pupil or retina capable of nocturnal vision or just like darkness. They are afraid of light, obviously because it can nearly blind their vision to see, they like to see in darkness or their eyes are not adjust to the sensitivity of light. Some examples are shining metals or objects, mirrors, and sources of light(like the sun). They are afraid of water because they either want to stay dry, hypothermia, or hygiene issues. Now I don't know how people with rabies can grow fangs that can be of 2 inches or more...The religious things tide into destroying vampires...well, I don't know how that got started but light can kill vampires, I think. Vampires may originate from people contacted with rabies, not sure if that's the case, but you may prove my information is nonsense or dislike opinion. The transformation of the bat, I don't know how that came from. Not all vampires are evil.
