Moss rafting

I dreamt last night, in the minuscule amount of time that I slept, that I was in a large park that was full of people and trees. The ground was covered with soft, bright green moss. There were tubes and long lengths of slip and slide like material which people were riding around on in rafts. Throughout the dream, different people were in the front of my raft but I was always in the back. No matter who was in the front, they would always jump off right before we went into one of the darkened tubes, leaving me alone with no way to steer. I think there was more, but I woke up a lot during this dream so it is hard to tell what was part of being awake and what was part of my sleep.
