Dreaming of being in a graveyard, especially during a family event like a funeral, can often symbolize feelings of loss, change, or reflection on family dynamics. Since you mentioned that no one was sobbing and it seemed like some time had passed since the death, this may indicate that you are processing grief in a more subdued way, perhaps reflecting on the memories of your aunt rather than experiencing raw sorrow.
The presence of your mother and her cousin might suggest a connection to your family's history and heritage, highlighting the importance of family relationships during times of loss. It could also signify a need to confront or acknowledge familial issues or emotions that may have been suppressed.
Consider what emotions you felt during the dream and how they relate to your waking life. Are there any unresolved feelings regarding your aunt or family members? This dream might be encouraging you to reflect on those connections and perhaps find closure or understanding regarding family matters.
Overall, take this as an opportunity to explore your feelings about family, loss, and the passage of time.
