Dreams involving the loss of a parent can evoke deep emotions and often reflect our subconscious feelings about relationships, grief, and unresolved issues. Here are some insights that might help you interpret your dream:

1. Fear of Loss: The death of your father in the dream may symbolize a fear of losing him or a significant figure in your life. It could also represent a fear of change or the unknown, especially as you navigate your teenage years.
2. Processing Grief: Experiencing your father's death and its impact on your family, including your mother's sorrow, suggests that you may be processing feelings of grief or loss, whether related to your father or other aspects of your life. This could be a representation of your own emotional struggles or observing someone else's pain.
3. Support and Connection: The presence of friends like Kevin and the act of hugging him while crying indicates a need for support during tough times. This part of the dream may suggest that you value your friendships and lean on them for emotional comfort.
4. Anxiety and Overwhelm: The feelings of anxiety you experienced in the dream, especially in public settings, could reflect real-life stresses or pressures you're facing. This may relate to school, social situations, or changes in your life.
5. Reality Check: The moment you woke up to see your dad in your room might symbolize a return to reality or a reminder of your father’s presence in your life, contrasting the grief you felt in the dream. It may also represent a desire to reconnect with him.

Overall, this dream seems to be a complex reflection of your emotional state, dealing with themes of loss, support, and anxiety. Consider exploring these feelings in your waking life, whether through conversation with someone you trust or through creative outlets like writing or art. It may also be helpful to reflect on your relationship with your father and express any thoughts or feelings you have towards him.
