My personal understanding is that in fact, the five girls are all schizophrenia of the heroine alone.
At the moment when the mental hospital turned into a nightclub, it was already clear that the heroine had already begun to go into a panic. Or the brain is not normal. . . . Because even if it is really a nightclub, the boss man doesn't need to wear eyeliner. If he really wants to apply eyeliner, his stepfather doesn't need to wear a priest's costume and apply blush. . .
And then I felt that every time I listened to that kind of music, the protagonist was not sleepwalking or attracting other people, but started to go crazy. . . . Destruction, stealing, burning toilets.
In fact, each girl represents a personality, impulsive (short hair, impulsive to do things), rational (long hair), timid (the whistleblower, the collapse is too unnatural, it should be a pure personality relationship). . . Etc., etc.
Then the understanding of the ending is. The heroine was still unable to escape. But the rational part was released with the surgery. That is, to get on the death train to meet Mom. Shorthair and Longhair seemed to say that she was going to tell her mom that she loved him or something. I also think that the female protagonist told the female doctor that she was going to help others escape or something, so that the female doctor later said that she helped people to escape.
