This kind of dream is called absurd dream.
In other words, the owner's car was knocked over, and the owner should be angry, but the owner smiled in his dream.
This is absurd in reality.
Then why did you have this dream?
First of all, the images of cars and dirt in the dream content may come from the life experience of the day.
But these are just disguises of dreams.
Because lz's subconscious has absurd concepts.
For example, lz met a person he hated that day, but he wanted to please him for one reason or another.
Then the subconscious will find it ridiculous (please the people you hate)
So I will have such a dream.
Lz can recall whether there was a similar experience on the day of dreaming.
You can see your subconscious judgment about that from this dream.
I hope it helps you.
