Dreams like yours, particularly those involving intense scenarios like watching a murder, can evoke strong emotions and leave you feeling unsettled. Here are some interpretations and insights based on the elements of your dream:

1. Third-Person Perspective: Observing the events from a distance may indicate feelings of detachment or powerlessness in your waking life. You might be witnessing events unfold around you without being able to intervene.
2. Murder and Death: These themes often relate to transformation or significant change. It might not be about literal death but instead symbolize the end of a phase in your life, such as a relationship or a job. The act of murder could reflect feelings of frustration or a desire to eliminate something troubling in your life.
3. The Father Figure: The unconscious father could represent authority, guidance, or protection in your life. His struggle to return to his daughters might symbolize feelings of responsibility or the desire to connect with family or loved ones.
4. The Doll's Head and Heavy Jar: The baby doll head may signify innocence or a lost aspect of childhood, while the heavy jar suggests burdens or responsibilities that weigh you down. This combination might indicate a conflict between wanting to protect innocence and feeling overwhelmed by adult responsibilities.
5. Water and Drowning: Water often symbolizes emotions. Drowning may indicate that you feel overwhelmed by your feelings or situations in your life. The ocean's depth can signify the subconscious mind, suggesting you may need to explore deeper emotions or unresolved issues.

Overall, this dream could be urging you to confront feelings of helplessness, the need for change, or the impact of responsibilities on your life. Consider what aspects of your life feel burdensome and how you might address them. Reflecting on your connections with family may also provide clarity.
