I was wondering could it be possible that not just Lucy was schizophrenic but everyone who entered that house was? Lucy killed Peaco and then died(suicide), Dolores killed her husband and then died(suicide). Rakan was killed by the demon, perhaps for disobeying the orders? Then Dwayne kills his family then himself. I feel that there may be a Visage 2 one day, maybe we would play a new resident in Visage 2 and we would play the character being tormented by the demon.
Or, could this be like Five Nights At Freddy's, and it's all just a scary dream??
