Dreams involving parents and themes of death can be quite intense and often reflect deep-seated emotions or conflicts. In your dream, the decision of your parents to take you to a mental health professional might symbolize a recognition of your struggles or issues that you feel need addressing. This could indicate a desire for support and understanding in your waking life.

The idea of your parents wanting to "start again" with you suggests feelings of inadequacy or fear of not meeting their expectations. It may also reflect your own fears about change and the pressure to conform to certain standards. The casualness of their intent to kill you might indicate that these feelings are deeply ingrained and possibly overlooked in your real life.

Your realization and resistance to dying in the dream is a powerful moment. It suggests a strong will to survive and a desire for self-acceptance. This part of the dream may reflect your inner strength and a refusal to be defined by others' expectations.

Consider reflecting on your feelings towards your parents and any pressures you may feel in your life. It could be beneficial to explore these emotions further, perhaps through journaling or speaking with a trusted friend or therapist. Remember, dreams often serve as a mirror to our subconscious, highlighting fears, desires, and unresolved issues.
