What is the meaning of Kambili's dream on page 126?

My page number does not match yours. In general Kambili’s dreams are clues to how she feels about certain people and events. Since Kambili only rarely speaks her mind, her mind speaks for her. She dreams that she has Aunty Ifeoma’s laugh because she wishes she could talk as freely and energetically like her aunt. When Amaka is deriding her, Kambili dreams her cousin is flushing her down the toilet. Kambili’s dreams are a gateway into her mind.
