Thank you for sharing your dream. Dreams about past experiences, especially those involving significant relationships and uncomfortable situations, can reveal a lot about your current emotions and unresolved feelings.

1. High School Setting: This often symbolizes a time of growth, learning, and social dynamics. It may indicate that you are reflecting on your past, particularly your experiences with relationships and how they shaped you.
2. Old Job: Working at a job you hated suggests feelings of being trapped or revisiting negative aspects of your past. It may indicate a fear or anxiety about being stuck in a situation that doesn’t bring you happiness.
3. Ex-Boyfriend "F": His presence could symbolize unresolved trauma or lingering feelings from that toxic relationship. The fact that he is in your dream might indicate that you are still processing those experiences and how they affect your self-esteem and current relationships.
4. Disabled Child: This figure may represent vulnerability or feelings of discomfort in social situations. Your reaction—yelling and pushing his hands away—could reflect your need for boundaries and your struggle with feeling safe and respected.
5. Running into Ex "O": The coldness of "O" contrasts sharply with your usual interactions, suggesting a shift in how you perceive past relationships. This may indicate feelings of betrayal or disappointment, reflecting your emotional state and how you feel about past connections.

Overall, this dream seems to highlight themes of discomfort, unresolved feelings from past relationships, and a desire to establish boundaries. It may be helpful to reflect on what lessons you have learned from these experiences and how they can inform your current life. Consider focusing on self-care and establishing boundaries in your relationships moving forward. If these feelings continue to weigh on you, talking to someone you trust or a professional may provide additional support.
