Dreams often reflect our subconscious thoughts, feelings, and concerns. In your dream, your mother going out with a recently released prisoner may symbolize a fear of change or unexpected influences in your life, particularly regarding someone you care about. The fact that she begins smoking—something she has never done before—could represent anxieties about negative changes or habits that can arise from new relationships or situations.

Your act of throwing away the cigarettes might signify your desire to protect your mother or your values, and it reflects a struggle against changes you perceive as harmful. This could also indicate a deeper concern about the choices of loved ones and how those choices may affect your life or family dynamics.

Consider reflecting on your relationship with your mother and any recent changes that may have been occurring in your life or hers. Are there any new influences or changes that are causing you discomfort? This dream could be prompting you to communicate your feelings or concerns with her in a constructive manner.
