I believe the conflict that slavery was becoming worse is the answer. When reading, the author wanted you to understand that the US had tried to fix the problem of slavery using the Missouri Compromise. Although, as you can see, it didn’t seem to work XD. All in all, I just think the author was trying to say that the problem of slavery had gotten worse.
At the beginning of the story he felt confused and scared. He was trying to figure out if it was all a dream or if it was real. He asked his mother and found out it was not a dream. And when he found it it was true he thanked his mother.
What passages?
