Judging from your dream.
Children represent their vulnerability or desire for love. This wounded, self-centered part of your heart deserves at least conscious self-love. Only in this way can this child part in your heart grow and mature.
It can symbolize your pure, innocent and true self: that is, your true appearance, different from the various external environments you come into contact with. The way conditions are formed. A symbol of your personality or a new development in your personal life.
Dreaming of a dog barking at you can show that someone around you is guiding you or hindering you. The symbol that wants to bite you has a warning or a warning for you.
I hope my analysis can help you.
