Given that Morbius is a "living vampire"( ie his vampirism is scientific and not supernatural in origin; he never died as a mortal and rose three days later- BTW is there a hint of religious symbolism here in mimicking Christ's resurrection?- although he shares their aversion to sunlight , he has none of the "true" vampire's fear of holy objects and places) what is his relationship with his supernatural brethren( excluding former fiance Martine Bancroft), esp Dracula, self proclaimed ruler of Earth's vampire community?

My guess is that although Dracula has most probably heard of Morbius, he and other vampires dismiss him as a"half-breed" because he is still a human being.
