Dreams often reflect our subconscious thoughts, feelings, and experiences. In your dream, several key themes emerge that can provide insight into your emotional state and relationship dynamics.

1. Setting of School and Eclipse: The school setting may symbolize a place of learning and growth, indicating that you may be processing lessons about relationships or personal development. The solar eclipse could represent a moment of significant change or an event that obscures clarity, suggesting that there are aspects of your relationship with Zach that are currently unclear or hidden from you.
2. Conflict and Fear: The moment when Zach is taken away by the principal and the mention of explosions hint at underlying fears or anxieties regarding your relationship. This could symbolize a fear of losing him or concerns about his behavior and choices, especially if you feel he might be involved in risky situations.
3. Packing and Moving: The act of packing signifies preparation for change or the need to let go of certain aspects of your life. This could reflect feelings of uncertainty about the future of your relationship and your desire to take control of your circumstances.
4. Intimacy and Trust Issues: The intimate moment followed by your question about infidelity highlights your internal conflict regarding trust. The lack of response from Zach may symbolize your fears about his loyalty and the emotional turmoil that comes with uncertainty in your relationship.
5. Emotional Conflict: The conflicting feelings of love and betrayal suggest that you might be grappling with deep emotional issues. Your love for him clashes with your concerns about trust and fidelity, indicating a need for clarity and communication in your relationship.

Overall, this dream seems to reflect your anxieties, fears, and unresolved feelings about your relationship with Zach. It may be beneficial to communicate openly with him about your feelings and concerns. Establishing trust and clarity can help address the issues that are surfacing in your subconscious mind.
