Duke Zhou dreamed that the girl he liked promised himself.

This is very simple, psychologically called wish realization, which is one of the characteristics of dreams.

It is a long-cherished wish for the girl you like to promise herself. My inner strong expectation came true in my dream: be good to myself.

You are right about one thing. You have a complex of depression in your heart. In order to untie the knot and balance the heart, the subconscious sometimes has a wish to come true. But after waking up, the contrast is bigger, the contrast is more obvious, and the dreamer's feelings are more lost.

Therefore, we should look at this matter rationally. Feelings are not a person's business, it depends on fate.
