As for who you are, I can't guess at random, but it may be an emotion in your heart.
The forest, sometimes representing romantic love, office, obviously means work, flower pond, which also means love. ...
Oh, I think you, the dinosaur in your dream, may represent your father. Your father, I think, is a very strict man. He is very strict with you. Now that you are an adult, you have your own love and work, but psychologically, you still can't get rid of your father's majesty and feel controlled.
You saw the end of the dream, didn't you? When you have the courage to face it, he is not a dinosaur, and his image is no longer so tall and terrible.
I also want you to have a good talk with your father directly in your dream to eliminate the shadow that you are not independent in your heart.
