In Alice in wonderland a Knave is a male servant.The white rabbit has a horn because he uses it to get the courts attention when he is about to address a topic and everyone is being loud. Everyone wants Alice to leave because she is growing out of control and she keeps knocking things over and being very obnoxious.The reason Alice is forgetting things so fast and is getting so big is because she is starting to wake up.The reason Alice is testifying even though she knows nothing is because she is a suspect its just like normal court room the have suspect then vote on who they believe committed the crime.The reason the sounds around her have affected her dream is because she is in the state of being asleep and being awake.
