Vampires are one of my favourite creatures and I have my own headcanons on how vampires work so here they are!
First of all, vampires don’t die from sunlight but it weakens them and they get sunburns very easily.
Almost all vampires are allergic to garlic but there can be some who are immune to it. However that is very rare.
Vampires can live for centuries, which often means outliving everyone they love and care for. I think of this quite often and it makes me sad :’<
A vampire can’t turn someone into a vampire by accident. Turning a human into one is always intentional.
Vampires do not need to feed on blood often. Most feed once every 2 or 3 weeks but this varies between vampires. They also have preferences on which blood type they prefer to feed on. Vampires can still eat human food but it doesn’t fill their hunger anymore.
Vampires still can’t enter a home without permission but they can enter public buildings just fine.
If you take a picture of a vampire, they will show up in the image as long as the camera doesn’t use silver in it. Same thing when it comes to mirrors/reflections. They show up on anything except silver.
They can turn into bats at will :3
The rate of how fast a Vampire ages depends on if they're an adult or a child. Child vampires age at a much simillar rate to which human children age while adult vampires age much slower than adult humans.
That’s about all, I’ll update this if I feel like it in the future! :D
