Dreams often reflect our subconscious thoughts, feelings, and experiences. In your dream, several themes stand out that can provide insight into your current life situation.

1. The Souq and Jewelry Shop: The souq represents a marketplace of ideas, experiences, and choices. Being in a place like a jewelry shop can symbolize value, beauty, and perhaps your aspirations or desires. Your mom trying on bracelets that don’t fit could indicate feelings related to expectations—either yours or those projected onto you.
2. The Dog Attack: Dogs often symbolize loyalty and instincts, but in this case, the aggressive behavior of the dog could represent a situation or person in your life that feels threatening or overwhelming. The act of killing the dog might reflect a desire to take control of a situation that feels dangerous or to eliminate something negative from your life.
3. Regret and Envy: When you shared your aspirations with your friend and sensed envy, it could indicate your own insecurities about pursuing your goals. The feeling of regret after sharing your ambition may suggest a fear of judgment or a lack of support from those close to you.
4. War and Destruction: The imagery of war and destruction could symbolize inner turmoil or conflict you are experiencing, perhaps relating to personal challenges or societal pressures.
5. The Hantour: Riding in a حنطور (horse-drawn carriage) with unknown people may signify a journey through life or a transition phase you are experiencing. It suggests that you are moving forward, even if the path is unclear.

Overall, your dream seems to reflect themes of ambition, conflict, and the desire for control in your life. It might be worthwhile to reflect on any current challenges you face, especially regarding personal aspirations and relationships. Consider what changes you might need to make to feel more secure and supported in your pursuits.
