Here is an excerpt from what Wikipedia has said about me and my 'kind', and yes, it does describe me pretty accurately:
"...strigoi are the troubled souls of the dead rising from the grave. Some strigoi can be living people with certain magical properties. Some of the properties of the strigoi include: the ability to transform into an animal, invisibility, and the propensity to drain the vitality of victims via blood loss. Strigoi are also known as immortal vampires."
PS: Immortal Vampires as in NOT Edward Cullen.
