Dreams involving the deceased can be profound and emotional, often reflecting our own feelings about loss, connection, and the afterlife. In your dream, the act of channeling your friend's son suggests a desire to communicate and find closure regarding his passing. The candle symbolizes light, hope, and guidance, indicating a search for understanding in a time of grief.

Your sister's role in the automatic writing may represent a connection to family and shared experiences in processing loss. The messages conveyed through the writing show a longing for connection and the reassurance that love transcends death. The mention of missing his family and specific memories, like his mother’s smile, highlights the importance of cherished relationships and memories.

This dream may indicate your subconscious processing feelings about mortality, love, and the bonds that remain even after someone has passed. It could also reflect your desire to support your friend during this difficult time. Consider how these themes resonate with your own experiences and emotions, and how they might guide you in providing comfort to those grieving.
