Dreaming about someone you have a history with, especially a friendship that has faded due to distance, can carry significant meaning. In your case, the recurring dreams about your friend suggest a few possible interpretations:

1. Emotional Connection: The dreams may reflect the emotional bond you share with your friend. Even though you haven't seen each other in years, your memories and the feelings associated with that friendship may still be strong. The dreams could be a manifestation of your subconscious longing for that connection.
2. Nostalgia and Reflection: Your dreams might also be a reflection of nostalgia for the past. You may be revisiting happy memories and experiences you had together, which could be a way for your mind to process those feelings of loss and longing.
3. Symbolic Representation: The activities you engage in during your dreams, such as traveling or taking care of each other, might symbolize aspects of your own life. For example, traveling together could signify a desire for new experiences or adventures in your own life, while taking care of each other might reflect a need for support and comfort.
4. Unresolved Feelings: While you mentioned that there are no romantic feelings, there may still be unresolved emotions regarding your friendship. The dreams could be an opportunity for your subconscious to explore those feelings, especially if you feel a sense of loss from the distance between you.
5. Interpersonal Reflection: The presence of your friend in your dreams could also indicate a need for connection or companionship in your current life. You might be seeking out qualities that your friend represents, or perhaps you are in a stage of life where you crave meaningful relationships.

Overall, these dreams seem to be a way for your subconscious to engage with the memories and feelings you have for this friend. It could be worthwhile to reflect on what aspects of your relationship or experiences with him resonate with you in your current life. If you feel comfortable, reaching out to him could also foster a sense of reconnection.
