Dream of

I was cycling in a woods, I don't quite remember but my sister was sitting in front. The bicycle was a one-seat bicycle. Then, we came to an intersection. The intersection was a very steep downhill road. At first, I doubt that I can cycle down because it is very steep. Then, I tried to cycle down although I was a little scared. While cycling down, it was really fast. Im afraid that my sister will fell but she didn't! At the feet of the hill, I thought we will fall because we were going to fast or the wheel of the bicycle might get off but it didn't. It just went smoothly and we manage to stop after a minute or two.
