Jason, dreaming of a good friend who has passed away can evoke a strong emotional response. This friend appearing in your dream signifies a connection to unresolved feelings or unfinished business related to their passing. The fact that his wife, who is still alive, was not present in the dream might indicate a separation between your thoughts of the past and your current reality. You are perhaps trying to reconcile memories and emotions that are tied to your friend's life and death.
The inability to remember what your friend said, if anything, suggests that the message or feelings he represents are not entirely clear to you yet. This could be a sign that there is something important you need to understand or come to terms with, but you are not entirely ready to face it head-on. It might be that you are grappling with thoughts or emotions that you have not fully processed, and your subconscious is urging you to pay attention to these unresolved aspects of your relationship with your late friend.
Furthermore, the absence of his wife in the dream could highlight a sense of isolation or loneliness in dealing with these emotions. It might reflect your own feelings of mourning or how you have processed the loss differently from others who were close to him. This separation could also symbolize your own journey in coming to terms with grief, where you might feel alone in your experience despite the presence of others who shared a connection with your friend.
