The idea that Fabian was able to somehow absorb the old man's ghost was absurd. But it made sense…
Fabian always thought that why vampires need to drink human blood in the first place. Why they couldn't just eat regular food. He then went to the bookshop and found a book on human anatomy. There he read that the food that humans intake gets converted into energy by human's stomach. And then the blood transports that energy to the whole human body.
If what he read was in fact true then this made no sense at all. If vampires drank blood to intake the energy from food that humans have, then it didn't make sense how the vampires were able to cure their illnesses. Logically if that energy was somehow able to heal all of his defects then all humans shouldn't have any defects at all. But that didn't seem to be the case.
