I know it's taken me forever to respond. But I thought I would anways.

Interesting that you mention all the different types of vampires. I really hadn't thought about it. My idea of vampires is confined to three major sources: Dracula (Bram Stoker's conception), Lilith (as written about in the book Lilith by George MacDonald), and the vampires in Sunshine (whose names have been forgotten, but the book is by Robin McKinley). Those three sources, though, give very different ideas of what vampires are. The common elements seem to be blood, power, and a sensuality. Someday I shall figure out just why vampires fascinate me so much.
