Sara: You're not real! You're not real! You're not real.
Jess: I don't hear anything... only silence.
Sara: I don't know if this forest made you psycho or you were always this crazy.
Sara: My sister Jess and I, we are identical twins. Once something happens to the one of us, the other one could tell. It's hard to explain, but I can just feel it. She's in trouble, and she needs me.
Answer: Sara spends much of the convoluted ending of this film in the midst of vivid hallucinations. Eventually, Sara dies, accidentally, at her own hands. She cuts her own wrists during a delusion where she believes she is cutting away the grasping fingers of her father's ghost. As she is dying, her body is dragged under the forest floor by Japanese "yurei." (ghosts). Her spirit remains to haunt the forest, lunging at Michi, the search party's forest guide, in the final frames of the film. Meanwhile her sister, Jess, has been rescued alive.
