Dreams about crushes and relationships often reflect your feelings, desires, and insecurities. In your dream, the act of buying pet fish with your crush could symbolize your desire to nurture a relationship or connection with them. The fish might represent new beginnings or the potential for growth in your feelings.

Forgetting to buy fish food may indicate a fear of neglecting important aspects of a relationship, or it could symbolize a worry that you might not be able to provide what is necessary for a connection to thrive. The jealousy you felt upon hearing about your crush's past relationship with a mutual friend suggests that you may have underlying insecurities about your worth or your place in their life, even if you are not officially together.

Working at Walmart and earning a good wage reflects a sense of stability and accomplishment, perhaps indicating that you are seeking security in your life or in your relationships. Overall, this dream may be prompting you to reflect on your feelings for your crush, your self-esteem, and how you handle jealousy and past relationships.

Consider what aspects of your waking life may be causing these emotions and how you can address them to find peace and confidence in your connections with others.
