Witches need human blood to perform retuals and to keep herself young and beautiful. Maybe Anamika's power was losing,so her hand become burned and the skin was lyk a old lady's. tht drop of blood healed it all. So Anamika is not a vampire or anything,i think she is a witch,a very old witch...
But vampires bodies are frozen so how come they can be healed? 😲 I think she is some dayan or pichhal peri type thing.
