Hi Natz and welcome,
I don't tend to believe people can be an actual Vampire, except the ones who actually like to go and drink blood (not the bite your neck type of way just the normal drink blood kind of way) suppose they could be class them as a Vampire of sorts though I just think their a bit dereanged but different strokes for different folks, some people might think think I'm deranged aswell Lol!
And if you pratcise spellcraft then I guess you are a Witch.
I only use my own spells because I know they work for me.
There's no steadfast rule that says you need to have an element some people are drawn more to one than another, but you can work with them all.
If you need help and I'm albe to help I will, just ask.
Love and Light
