However, most people who emphasize that they are unmarried are girls, so I will explain this dream according to the fact that you are a woman.
Analysis of dreams
Most of the children in the dream represent their immature selves and their childhood memories and feelings, rather than nobody.
The place is in the first grade classroom, where life learning has just begun. The female teacher symbolizes your own wisdom and rationality.
You explain to children who don't understand. This is because you want to take care of all the new things in your life.
That disobedient little boy may symbolize some secular realities and concepts in life.
Especially fucking words, saying that there is a future and a way out if you don't study.
I think, first of all, it may be your own childhood. I feel that your mother's influence on you is not positive, which has affected your own outlook on life and values, as well as your current living conditions.
Secondly, this phenomenon exists in reality. Thinking about it, I feel that being influenced by bad influences from an early age will destroy good learning conditions and foundations.
If you are a girl, then the dream female teacher is your own incarnation. If you are a man, I think the little boy may imply your own state, a kind of worry.
