Anyone ever think about the hands or other things may represent people looking for her?
She may of went to a boarding school, and she had much trouble in math, without any friend at all, really.
Then one day as she is walking out in town she is kidnapped (hence the hands in many places throughout the game, trying to grab her as she runs away) due to the fact that her parents are very rich people, and her kidnappers want money, lots of it.
her kidnappers put her in a small place (toringen) refusing to let her out,
whenever she tries to get out though, she succeeds, but soon becomes terrified. She recognizes nobodys faces, looks at a tv screen an a store and sees a murder story concerning her friends(girls from the white desert), except for the one friend that went overseas (poniko) in terror, she runs around frantically, just to be caught by her kidnappers again. At this she starts wishing she had a disguise, SOMETHING as a disguise. (many effects that merely change her appearence in the game)
so she gets locked up again, without any way out.
Isolated, locked in the room, she begins wishing for lots of things, maybe to hear her mother play the flute again, or that she could somehow find a knife that could help her get out of the place.
She wants to leave, but she cant, the door is locked, and blockaded. (which is why, when she is awake, she wont open the door and shakes her head instead, this looks more like a "I cant" gesture than "I wont")
There are people below her, when she goes onto the balcony, she tries to call out to them, but they cant hear her, close, but she cant reach them (toringen girls partying in the desert, she can see them, but not reach them). Eventually, she starts purely sleeping all the time, reality and hopes distorted in her dreams. Whenever she gathers all that she had wished for over the past time, she realizes its mere dream, that she will die if she doesent actually do something(ghost effect,ghost of her in a blood vessel stream, others call it hell maze, but I think it looks like blood vessels), it isnt real, so she drops them in the nexus, inside eggs, somewhat like her stuck in the same room. At the end of the game, the step ladder isnt there, she merely jumps over, hoping somebody will see her and catch her before she dies, because she no longer cares which way it is, there is more hope jumping than staying in that room without anything to eat or drink. The stairs were a representative of her thoughts finally climbing to that conclusion. she is caught, but still seriously injured, and taken away by an ambulance, leaving bloodstain on the street. The jellyfish for her dreams come in at the end because inside her dream world that we experienced, she is dead, never to go back to those dreams again.
