Dreams about siblings often reflect your relationship with them or aspects of yourself that you associate with them. In your dream, searching for a place to eat symbolizes a desire for nourishment or fulfillment, both physically and emotionally. The obstacles you encountered, like the crowded area and the decrepit restaurant, might represent feelings of frustration or disappointment in your current circumstances or relationships.

The contrast between the dirty restaurant and the cleaner one could suggest a desire for better experiences or environments in your life. Your insistence on leaving the unpleasant place may indicate your unwillingness to settle for less than what you deserve or desire. The fact that you woke up before you could eat might imply that you feel like you are missing out on something important or that you haven’t fully realized your goals yet.

Your sibling's frustration may represent a conflict between wanting to support each other and pursuing your own path. This dream could be a reminder to prioritize your well-being and values, even if it means taking a different route than those closest to you. Consider what areas of your life you might need to 'clean up' or improve in order to achieve the fulfillment you seek.
