Dreaming about the death of an uncle, especially one you didn't know well, can symbolize a variety of emotions and thoughts. Here are some possible interpretations:

1. Processing Loss: Even if you weren't close to your uncle, his death in your dream may represent a way for your subconscious to process the concept of loss and mortality. It might prompt you to reflect on your own life and relationships.
2. Family Dynamics: This dream might indicate underlying family issues or dynamics that you haven't addressed. It could be a call to explore your feelings about family connections or unresolved matters.
3. Change and Transition: Death in dreams often symbolizes change. Your uncle's passing could represent a transition happening in your life, whether it be personal growth, a new phase, or the end of something that no longer serves you.
4. Reflection on Life: The dream might encourage you to reflect on your own life and the legacy you wish to leave behind. It could be a reminder to value relationships and consider how you interact with those around you.
5. Unresolved Feelings: If you have any lingering thoughts or feelings about family or relationships, this dream may surface those issues. It can be an invitation to explore what those feelings are and how they affect you.

Consider how the dream made you feel and any context from your waking life that might relate to the themes of loss, family, or change. Engaging with these feelings can provide valuable insights into your current life situations.
