He said that if something happens, I will open it myself: it means that for some reason, I can't rely on the other side, or the dominant position is temporarily on myself. Your relationship with him is the key to dream interpretation.
I dreamed that I didn't notice that there was no venue and no roof. Sometimes I can't drive, but I run with my ankles: this means that I lack control over my life and can't drive, which means that I sometimes feel that I can't make progress. Running with a person's pedal represents small progress, and it takes a lot of effort to make progress.
Cross a very straight and beautiful bridge, with blue water on both sides: the bridge represents a key to life and is the boundary between the present and the future. Crossing the bridge means that you have the ability to move on.
At first, I dreamed that the car was driving very slowly, but later I realized that the car was driving very fast and I finally got home: it meant that I could control myself and my life better and better.
Generally speaking, this dream is related to your growth, which shows that you are extremely resilient and will become more and more mature in the journey of life, and some things can't beat you. Good luck!
