Recurring dreams often indicate that there's something in your waking life that needs attention or resolution. In your case, walking through violent school hallways filled with bad students might symbolize feelings of anxiety, fear, or conflict in your life. Schools often represent a place of learning and social interaction, and the presence of "bad students" may reflect negative influences or toxic relationships you are encountering.
The other kids trying to reach a safe place could represent your desire to find safety or support amidst chaotic or challenging situations. This dream might suggest that you are feeling overwhelmed or threatened by certain aspects of your environment, and you are searching for a way to escape or find peace.
Consider what is currently happening in your life. Are there situations or people causing you stress? Reflecting on these elements can help you gain insight into the emotions that are surfacing in your dreams. It may also be helpful to think about ways to establish boundaries or seek support from others to navigate these feelings of danger or discomfort.
