I fell asleep on my couch today. I dreamt I was a little kid at an amusement park and I lost my balloon. As I chased after it I saw a little girl get killed. What does that mean?

An amusement park in a dream can be a symbol of how you see your life.

Since a balloon can symbolize the ability to rise above your current problems, perhaps losing your balloon at the amusement park means that you find yourself unable to get away from your difficulties.

Death in a dream often represents the end of something old and the start of something new, so perhaps the dream is telling you that you need to make a big change in your life in order to solve some of your problems.
