Dreaming of power lines and pylons can symbolize energy, connectivity, and the flow of information or emotions in your life. The spinning and knotting of the lines may represent feelings of chaos or a lack of control over certain situations. It could indicate that you are experiencing stress or complications in your relationships or responsibilities.

The fact that your neighbor's electricity went off could suggest concerns about the impact of external factors on your stability. Your instinct to take a picture may reflect a desire to document or make sense of the chaos around you. Additionally, preparing chargers and lanterns indicates a proactive approach to potential challenges, showcasing your resourcefulness and readiness to handle difficulties.

Overall, this dream may be urging you to assess areas in your life where you feel overwhelmed or disconnected and to prepare yourself mentally and emotionally for any changes that may come your way. Consider what aspects of your life need attention or organization to restore balance.
