What happened in the dream has no special meaning.
People and things that you often contact during the day will leave an impression in the noise. At night, your brain will "cramp", so you will dream strange things.
It's like a cramp in your leg after running for too long.
When you encounter something similar to the original brain cramp in your life, your brain will immediately take out the records that have been cached for a long time, and you will feel that you are looking forward to the future.
So don't worry too much. Relaxation is the most important thing.
