Dreams about travel, especially to significant places like Mecca, often represent a journey of self-discovery or spiritual growth. Meeting people from your past may indicate a desire to reconnect with aspects of your life that you value or miss. The positive reception you received suggests that you feel appreciated and respected in your social circles.

Adopting a homeless dog in your dream can symbolize compassion and a willingness to take on responsibilities that others might overlook. It may reflect your nurturing side or a desire to help those in need, but it also indicates a potential struggle with resources or commitments (as seen with the flight you missed).

The nicely set table with cake at the end of the dream is a strong symbol of reward and celebration. It suggests that despite the challenges you face (like the delay caused by the dog), there is still joy and fulfillment awaiting you. The cake could represent a sweet outcome or success that comes from your choices and actions.

Overall, this dream may be encouraging you to embrace your compassionate nature while recognizing that sometimes, the decisions you make can lead to unforeseen consequences. However, it reassures you that there are positive experiences and rewards on the horizon. Consider reflecting on your current life situation to see if there are areas where you might want to show more compassion or take risks that could lead to fulfilling experiences.
