My group had a very helpful and insightful discussion on CoverItLive. Scott brought up the trial scene and how Alice was kicking and stepping on the jury.
The trial is my favorite part of the story. I see it as Alice waking up. She is growing because she is waking up from her dream.
I personally think her adventure in Wonderland was a dream. My group discussed why we believed it was a dream.
The great detail and strangeness of the story can only be a dream. What else would it be?
During the trial scene, Alice becomes very defensive. Alice becomes angry. She is not afraid because she is now so much larger than the rest of them. She is braver now.
Alice begins to kick and step on the jury. To me, this seems like she is having a nightmare. Sometimes when people are having nightmares, they kick in their sleep. I think that could be a reason why Alice was kicking and knocking people over. She was doing it subconsciously in her sleep.
