Undeath

After the vampire bit me, I passed from life to undeath.

"That invitation was made before your death. Or undeath. Or whatever you call it." "Rebirth," he whispered. "Begone!"

No one could decide for certain whether the specimen as a whole were alive or dead, only that some organ function remained and the cells continued to regenerate, albeit at a much slower rate than before their death. Or undeath.
