Dreams about people changing in unusual ways, such as your boyfriend having fish eyes, can symbolize feelings of confusion or a lack of clarity in your relationship. Fish are often associated with depth and the unconscious, so this could indicate that there are underlying feelings or issues that you may not be fully aware of.

Consider how you feel about your boyfriend in your waking life. Do you feel connected and understood, or are there aspects of the relationship that seem unclear or unsettling? This dream might be urging you to explore your feelings and communicate openly with your partner about any concerns you may have.

Reflecting on the overall context of the dream and your emotions during it can provide further insights.
