Dreams involving deceased loved ones can be particularly poignant and often carry deep emotional significance. In your case, dreaming of your ex-lover being alive and in a friendly relationship with you might symbolize unresolved feelings or a desire for closure. It could reflect a longing for the connection you once had and the positive memories associated with him.

The setting of Ireland, a place you cherish, suggests a sense of comfort and happiness. It might represent a safe space for healing and nostalgia. The cooperative effort in the dream with children adds a layer of positive family dynamics and teamwork, indicating that you may be seeking harmony and collaboration in your current life, possibly in relationships or in parenting.

This dream could also be a manifestation of your subconscious processing the past and your emotions surrounding his death. It may be encouraging you to embrace joy and connection in your life, even if it comes from memories of the past.

Consider reflecting on your feelings about your ex-lover and what aspects of that relationship you may still hold dear. It might also be beneficial to explore how you can incorporate those positive feelings of teamwork and joy into your current life.
