Your dream seems to be rich in detail and filled with various emotions, highlighting relationships, social dynamics, and personal challenges. Here are some possible interpretations of the key elements in your dream:

1. Returning to School: Going back to school often represents a desire for learning, growth, or a return to familiar settings. It might signify that you're reflecting on past experiences or preparing for new challenges in your life.
2. Family and Social Interactions: The presence of your family, especially your mother's side, could indicate a longing for connection or support from your loved ones. However, the tension with certain individuals (like Danial and Bre) suggests possible underlying conflicts or feelings of being judged.
3. Kyrie's Behavior: Taking Kyrie to the book fair could symbolize your nurturing instincts or desire to help others, especially those who may be struggling (like Kyrie was with grandma). It may reflect your feelings about responsibility within family dynamics.
4. Confrontation with Nikoria: The interaction with Nikoria, where she looks shocked, might represent unresolved feelings or conflicts with someone from your past. Your reaction of saying "Merry Christmas" could indicate a desire to maintain a cordial relationship despite any tension.
5. Shopping for Snacks: The act of buying food with your mom may symbolize self-care or the need to nourish yourself emotionally. The fruit you bought could represent a desire for health and sweetness in life.
6. Awkwardness with Parents: Witnessing your parents being intimate could evoke feelings of discomfort, perhaps reflecting your struggle with boundaries or a shift in family dynamics as you grow older.
7. The Phone Conversations: The phone calls with Danial, Bre, and others seem to indicate feelings of being overwhelmed or ganged up on. This could symbolize feelings of insecurity or the pressure you feel from social circles. The recurring theme of not having something (like the charger) might represent feelings of inadequacy or the fear of not being able to meet others' expectations.
8. Feeling Misunderstood: Your strong reactions to feeling like others are “talking shit” on you suggest a deeper concern about how you are perceived by others. This may reflect your anxiety about social acceptance or fear of betrayal.
9. Emotional Release: The tearful moment at the end of the dream indicates a need for emotional expression. It may be essential to find healthy outlets for your feelings and communicate openly with those you trust.

Overall, this dream suggests a complex mix of emotions regarding family, friendships, and personal identity. It may be helpful to reflect on these relationships in your waking life and consider any unresolved tensions or feelings of vulnerability. Engaging in open communication with loved ones or seeking support could help alleviate some of the weight of these emotions.
