~~ The Dream exists to enact the Moon Presence ' s vengeance . She has her moonscented hunters kill Great One children to deprive humanity of umbilical cords and thus eyes on the inside , suppressing evolution into higher forms . Instead , people who mess with blood turn into beasts and are slaughtered by other hunters . We just end up killing each other , and will eventually go extinct like those who lived in Loran . Djura is right this is all madness . ~~ Oh uh , I mean , err , it ' s there because the Moon Presence made a contract with Laurence to provide him unkillable , incorruptible hunters . This is implied in a note found on the Lecture Building ' s second floor as well as in the description of one of the umbilical cords , and from Gehrman ' s sleeptalking dialogue that asks Laurence what ' s taking him so long . Since it ' s a contract , both parties get something out of it Laurence got his hunters , but the MP can use them for her own reasons as well . Mergo is a onetime occurrence for our hunt only . The red moon descended on Old Yharnam in the past , which is when it was burned down . Djura was likely the moonscented hunter that evening since he recognizes us as dreaming . Eileen at some point was a moonscented hunter , but as to what she had to do , we can only guess . There ' s a big possibility that the red moon is drawn by the presence of Great One children , so something like the Mensis shenanigans we deal with in the game could ' ve happened then . Moonscented hunters in the past probably do the same things we do in the game , only with a less apocalyptic setting . Also , slight correction , the Hunter ' s Dream continues to exist in every ending .
