Dreams involving deceased loved ones can often be deeply emotional and significant. In your dream, seeing your cousin at the school run may symbolize your ongoing connection and the memories you have of him, particularly in relation to family and the roles he played in their lives. The shock you felt could represent your struggle to accept his passing, while the fact that his children could not see him may highlight the idea of loss and the impact it has on those left behind.

When you communicated with his partner about seeing him, it reflects your desire to share your experiences and perhaps provide comfort to those who are grieving. Your cousin's presence in the dream, especially as he quietly watched over his children, indicates a protective and loving spirit, suggesting that he may still be around in some way, even if not physically present.

The dramatic change in the dream, with the blinds flapping and signs of his presence, points to the emotional intensity of your grief and the belief that our loved ones can still communicate with us in some form. It can also symbolize a yearning for signs of reassurance that they are at peace.

Overall, this dream can be seen as a way for your mind to process grief and maintain a connection with your cousin. It might be helpful to reflect on the feelings it stirred within you and consider ways to honor his memory in your waking life, perhaps by sharing stories or spending time with his children to keep that connection alive.
