In dreams, cliffs represent difficulties, traps, restrictions, etc.
Because the driver started taking you off the cliff, the driver can be the villain.
In the dream, you and your mother fell off a cliff together, which not only shows that you are going to encounter difficulties, but also shows that you don't know whose fault the villain behind you is.
Then you didn't die after falling off the cliff, but you were injured. That is to say, although you are somewhat limited after entering another environment, you don't lose much, so you can cheer up slowly.
At the same time, we should also prevent mothers from encountering similar difficulties.
