Sally often speaks of her stuffing of dried leaves. For example, her leaves rustle or churn with her emotions. She wishes Doctor Finkelstein had stuffed her with something less associated with death, like air-puffed cotton or rose petals that would reflect the kind of person she wishes she was. Her stuffing symbolizes her sense of not being what she should be.

It took the combination of both those parts of herself to defeat the Sandman.

Symbolically, doors represent both challenge and opportunity. By stepping over the threshold, the protagonist signals acceptance of the task ahead.
