Dreams about reconnecting with old friends can often reflect a desire for closure or unresolved feelings from the past. In this case, dreaming of your old best friend and learning about his father's death might symbolize a need to process feelings of loss or regret, either regarding your friendship or in your own life.

Your friend's indifference in the dream may indicate feelings of helplessness or a sense that you cannot change the past. This could suggest that you are grappling with feelings of guilt or a desire to make amends for lost time.

Consider what this dream is prompting you to reflect on in your waking life. Are there unresolved relationships or feelings you need to address? It might be beneficial to reach out to old friends or to take some time to reflect on your feelings about loss and connection. Ultimately, this dream may be encouraging you to seek understanding and healing in your relationships.
