Paradox

On page 226, I came across a paradox. Bill and Jake are talking about the fiesta and Bill calls it a "wonderful nightmare". How can something be wonderful, but be a nightmare? Nightmares are scary dreams that impact a person in a negative way. However, something wonderful makes a person feel good and allows to have good memories. In a sense, I can see why Bill would call the fiesta a "wonderful nightmare". It is wonderful because it is a fiesta! Parties are always fun and memorable. But, it resembles a nightmare because of the troubles that arose. Cohn got angry and hit Jake and Romero. They ended up hurting their friends. Even though at first we would never put wonderful and nightmare together, in the end, we can kind of see the truth in the statement.
