In real life, we can't get the majesty and power of the emperor, so the dragon doesn't represent the throne, but the meaning expressed in this dream has an influence on us. This is a symbol of realizing one's wishes. You mentioned that "it's called dragon, its scales are tight and beautiful, and it has feet", so this wish is beautiful and realistic. "Find a way to catch" is to work hard for this.
Just as I was about to catch it, a child from her neighbor jumped in and caught it. I asked him for it, but he wouldn't give it. The result didn't satisfy you, indicating a sense of loss. It should be emphasized that this child is "that child's brain is not very flexible." An unfavorable life saved you, and your self-esteem was hit.
In addition, snakes and earthworms are often interpreted as being related to sex in psychology, which can be judged according to their own actual situation.
