Philosophy of Nothing Much PNM

Carnivorous Humans, basically vampires and similar creatures, have existed for about as long as humans have. However the two have never gotten along. About 50 years ago society changed however with the discovery of artificial substitutes for human biomass. This strange substances made it possible for such beings to get along with humans with little issue. Its been about a generation since this occurrence and the recently fully grown Iris, one of these Carnivorous Humans, finds herself being whisked away to what can only be described as the past each night only to return the next day. Will she ever figure out why or just end up burning out?
