Dreams involving deceased loved ones can be particularly poignant and often carry significant emotional weight. In your dream, your cousin's appearance as a giant may symbolize the larger-than-life impact he had on your life, reflecting how deeply you feel his absence. His wobbling walk could indicate the confusion or instability you might be experiencing in your own life following his passing.

Your act of asking him if he was okay and offering your shoulder suggests a desire to provide comfort and support, not only to him but also to yourself as you navigate your grief. Walking to his mother's house could represent a journey through memories or a need to connect with family during this difficult time.

The transition to him appearing outside the house with his uncle could signify the connection between family members, both living and deceased, and the continuity of relationships despite loss. Seeing a younger version of him eating chocolate may symbolize a return to happier, simpler times and could reflect your longing for those joyful moments you shared.

Overall, this dream may be processing your feelings of grief and loss while also celebrating the joyful memories of your cousin. It might be helpful to reflect on what he meant to you and how you can carry his memory forward in your life. Engaging in conversations with family members about him could also provide comfort and help you all heal together.
