A self-transforming scooter gets jammed up my pants when I fall in the river

I'm on vacation, babysitting a sister and brother with a male I don't know. We had let the kids do something the parents wouldn't approve of and it had caused a mess; the kids were cleaning it up before their parents arrived home.

My brother is with he parents arrived home along with when they get back. I need to make arrangements with my brother to return from vacation. He is standing right in front of me in the back yard when begin to call him on my cell to make the arrangements. When I realize I didn't have to call him because he was standing right there, I think is very funny and tell the others what I was about to do but no one laughs.

I'm walking down a steep and wooded embankment towards the Mississippi and lose my footing. I slide down the embankment into the water. "Was there barbed wire in there?" my brother asks. As I feel a shooting pain on my left leg, I tell him there was. I can't see a way out of the river until I entirely cross it. I swim back and pull myself up onto a gravel area by a patio with people grilling on it.

Something very large has wedged itself all the way up my left pant leg. In extreme pain, I rip my jeans to get it out. It's a Razor style scooter! My leg is severely injured and I have to pull myself with my arms. There are many people around, in bleachers and on the sidelines of several races. Two of the races have to be stopped so I can pull myself across the tracks, carrying the scooter along with me. I pass a few people who remember me from high school, I don't remember them.

Unlike other injury dreams, it doesn't seem like anybody should be helping me, I'm just making my way back to where my brother is. When I make it back, the scooter has transformed into something also sort of like a roulette wheel and marble game, except there's only one roulette slot and an non-rotating catapult for the marble in the middle.

For some reason, I again swim across the river. There are still lots of people around everywhere. A girl, who owned the scooter in the river approaches me. I tell her there's no way I'm giving the scooter back, I got really injured and ruined an expensive pair of jeans. By now, the scooter has transformed again: now it came with a carrying case and an enormous self-inflating mattress. A male wants to borrow it to smoke pot out of the catapult part; I let him. The girl who owned the scooter tells me she only wants the inflatable mattress. I give it to her.
