Dreaming of being chased can often symbolize feelings of anxiety or pressure in your waking life. It may reflect a situation or responsibility that you feel unable to escape from. The group of people you were with could represent your support system or shared concerns with others.
The act of tossing a brown powder that hides you suggests a desire for protection or a way to escape from your worries. The color brown can represent stability, grounding, and a connection to the earth, which might indicate a need for security in the face of challenges. This powder might symbolize a resource or strategy you possess to deal with your fears or obstacles.
Consider reflecting on what aspects of your life currently feel overwhelming or threatening. The dream may be encouraging you to find ways to shield yourself from stress or to confront the issues that are following you. It might also be beneficial to seek support from those around you, as represented by the group in your dream.
