This is really interesting. I guess I belong to the Dracula generation, maybe that's why I find other depictions of vampires at best boring.
Bella and all the gang of series finished the genre for me.
I did not know about the burial rituals. Fascinating.
As you said, old beliefs and practices die hard. No stone is heavy enough to keep them burried.
The sad thing is that real evil does not match any legend or myth, and it lives among us dressed casually or in fine clothes.
