Dream about scary fish suggests neatness and cleanliness. You are feeling picked on or harassed. You are trying to control what is being revealed about yourself and your character. It is a premonition for your experiences and how you need to learn from them. You are repressing some feelings in your life and they are manifesting in your dream.
Scary fish dream hints emotional secrets or activities. You have achieved something which you thought you could not do. You are being called on for support, either emotional support or physical support. It is sometimes your growth. You need to expand your knowledge and learning.
If you dreamt about scary fish:
There could be a battle going on between your heart and your head. Today’s interplay of celestial energies may indicate that your head tells you to go one way and commit to one particular plan, while your heart tells you something else. While it is true that you do need to think clearly about how to achieve your goal, only your heart can tell you what that really is.
