Dreams often reflect our subconscious thoughts, feelings, and experiences. Your dream appears to encapsulate several themes, including familial relationships, feelings of guilt or shame, and a sense of being unfairly judged or blamed.

1. Family Dynamics: Your mother and father represent authority figures in your life, and their presence may indicate feelings of pressure or expectations you feel from your family. The conflict with your mother suggests a struggle for independence or rebelliousness, especially regarding choices you make, like smoking.
2. Craving and Escape: The craving for a cigarette could symbolize a desire for relief or escape from stress or responsibilities. Running away barefoot and in short clothes signifies vulnerability and a wish to escape judgment or confrontation.
3. Chasing and Confrontation: The act of your mother chasing you could represent unresolved issues or feelings of guilt. It may indicate that you feel pursued by your own choices or the consequences of your actions. The persistence of your mother in the dream suggests that these feelings are hard to ignore.
4. Accusation and Innocence: The shocking turn of being accused of a girl's murder could symbolize fears of being misunderstood or unfairly judged by those around you. The feeling of being framed points to concerns about your reputation or how others perceive you.
5. Anger and Resolve: Your anger and determination to fight for your innocence reflect inner strength and a desire to confront challenges head-on. This could symbolize your readiness to face conflicts in your waking life, especially regarding family expectations or societal pressures.
6. Feeling Betrayed: The betrayal you felt from your mother can indicate a fear of disappointing loved ones or the feeling that they may not support you in difficult times. It suggests a need for understanding and communication within your family relationships.

In summary, this dream highlights themes of family dynamics, independence, judgment, and inner conflict. It might be beneficial to reflect on your current relationships with your family and any pressures you feel. Consider having open conversations with them about your feelings to alleviate some of the tension you may be experiencing.
