Your dream seems to be rich with symbolism and emotions that may reflect your current feelings and experiences in waking life. Here are some possible interpretations:

1. The Lady in the White Dress: The woman in the old, dirty dress could represent a part of yourself or someone in your life that feels neglected or unacknowledged. Her initial familiarity suggests that this may be linked to your past or a memory. The transformation into a frightening figure could indicate fears or anxieties that you are trying to confront but find overwhelming.
2. Chasing and Escaping: The act of being chased often signifies feelings of pressure, stress, or avoidance in waking life. This could relate to responsibilities, fears, or unresolved issues that you're attempting to escape from. The fact that you pulled someone else into the situation might suggest that you are seeking support or trying to divert attention from your own fears.
3. Zombie-like Figures: The people acting like zombies could symbolize feelings of being overwhelmed by societal pressures or the sense of conformity. They may represent aspects of your life or people around you that feel lifeless or unengaged, which might be causing you stress or discomfort.
4. The Girl Fighting: The girl you know trying to fight off a zombie could symbolize your concern for others or your empathy towards those struggling with their own battles. Her getting scratched might reflect your fear of being drawn into conflict or negativity.
5. Overall Feelings: The overall theme of being chased and the chaotic environment suggests a sense of anxiety or feeling trapped. It may be a sign that you need to confront certain issues head-on rather than avoid them.

Advice: Consider reflecting on what in your life currently feels overwhelming or scary. Are there situations or responsibilities that you are trying to escape from? Finding ways to address these feelings, whether through conversations, seeking support, or taking small steps towards facing your fears, could be beneficial. Journaling about your emotions or talking to someone you trust might also help you process these feelings further.
