Dreams that involve significant dates, especially those related to loss, can often reflect our emotions and unresolved feelings surrounding that loss. Missing the anniversary of your mother's death in the dream may symbolize feelings of guilt, regret, or a sense of disconnection from your memories of her.

This dream could be prompting you to reflect on your relationship with your mother and how her absence affects you. It might also indicate a desire to honor her memory or a reminder to acknowledge your emotions regarding her passing.

Consider what your mother meant to you and whether there are aspects of your grief or memories that you need to confront or express. It might be beneficial to take some time to remember her, perhaps by sharing stories with family or engaging in a ritual that honors her memory.
