Dreams involving family often reflect your relationships, emotions, and experiences with those closest to you. In your dream, the setting of a place where prasad (a form of religious offering) is sold suggests themes of spirituality, devotion, and perhaps the importance of tradition within your family.

The two containers and spoons may symbolize choices or paths in life, possibly representing different perspectives or decisions faced by you and your family. Your instinctive knowledge of which prasad to choose could indicate a deep connection to your familial values or beliefs, emphasizing your intuition and sense of belonging.

The conflict with the lady who commented on your actions may represent external judgment or pressure that you feel in your waking life. Your strong reaction suggests that you are protective of your family and the way you interact with them. This could indicate a desire to assert your feelings and boundaries in situations where you feel judged or misunderstood.

The scene with your grandfather discussing his impending death can be quite profound. It may reflect your subconscious processing of fears related to loss or the reality of aging within your family. Your father's reminiscing about childhood memories shows the importance of legacy and the impact of family history, while your mother's story about improving the sweets symbolizes nurturing and care in family dynamics.

Crying silent tears in the dream signifies deep emotion and perhaps unresolved feelings regarding loss, change, or the passage of time. The contemplation of your grandfather's death and the relationship with food may reflect concerns about life, nourishment, and the significance of shared meals as a metaphor for connection and the cycles of life.

In summary, this dream appears to be a rich exploration of your familial bonds, the fear of loss, and the comfort of shared memories. It may be helpful to reflect on your current feelings toward your family dynamics and any unresolved emotions you may have regarding life changes or the aging of loved ones. Consider discussing these feelings with someone you trust or writing about them to gain further clarity and understanding.
