Dreams come from psychology and thoughts. Dreams have no prophetic function, but they have symbolic significance.
Interpretation of dreams requires the dreamer to provide more detailed information, not just dreams. Because the information is not comprehensive, I don't know whether you are in trouble emotionally or professionally at present, so I can only try to understand this dream from two aspects for reference only.
Interpretation of dreams:
First of all, solve this dream from an emotional point of view.
The sea symbolizes emotional entanglements. You dream that the sea overflows and you start to run away, which means you want to run away from this relationship.
Small fish symbolizes lovers or relatives. You hold the small fish in your hand, don't give it up, and finally release it to the sea. Explain that you are reluctant to give up, compassionate, unwilling to let go, and unable to hurt each other. I hope each other will be happy and have a good home.
The big shark symbolizes bosom friends. The big shark tied with a rope saved you, which shows that you want to talk to your bosom friend about your troubles and hope that the other party can come up with a good solution for you.
This dream shows that your relationship is in some trouble. You want to solve them quickly, but you can't start. You want to escape, but you are worried about hurting others. You want to help, but you don't know who can help you So you're struggling.
Second, from the perspective of career to solve this dream:
The sea symbolizes danger and frustration. When there is a flood, you start to escape, which means that your life is facing difficulties or challenges, or you don't want to maintain the status quo intermittently.
Small fish symbolizes dreams. In times of crisis, you still hold the little fish in your hand. The little fish is dying. You give it oxygen and do your best to release it into the sea. Explain that although the reality is very severe, you still insist on your dream, unwilling to give up, not afraid of setbacks and challenges, and hope that your dream can be realized through hard work.
The big shark symbolizes salvation.
