I don't understand dreams. According to your description, my explanation is: in reality, you are eager for your own success, but the reality may not be ideal. There may be something that makes you feel a little tired these days. The little dragon in your dream is the embodiment of you who is eager for success. You dream of flying, but your head and tail are crushed by stones (occupational obstacles), which makes it inconvenient and difficult, but you still stubbornly destroy and drive away the enemy (dilemma), but this process also makes you exhausted.
Yes, it needs to drink water and rest. Isn't this the whole of life? Few people are good enough to become a phoenix and fly freely in the air. Life is bound to make mistakes. Treat it calmly and make unremitting efforts, and the goddess of success will take care of you one day. But when you need a rest on the way, slow down and rest. Don't just bury your head on the road and enjoy the scenery along the way. Life is more interesting and exciting.
I hope my explanation will make you relax. I wish you a smooth work and a happy day!
