Your dreams are rich with symbolism and seem to reflect a mixture of personal experiences and deeper emotions. Let's break down the key elements for interpretation:

1. The ساحة (Square): This could symbolize a public space in your life where you feel connected to others. It may represent a place of gathering or community.
2. The Moon: The orange-reddish moon you described may signify emotions or a transformative phase in your life. The colors can represent various feelings—orange for creativity, red for passion or anger, and brown for stability or grounding. The way it transformed into golden glowing plasma suggests an awakening or realization.
3. The Spaceship: The appearance of the spaceship and the glowing plasma could indicate a sense of exploration or new beginnings. It might reflect your curiosity about the unknown, your desire for adventure, or feelings of being in a transitional phase in your life.
4. Returning to the ساحة: This signifies a desire to revisit a place of safety, comfort, or belonging. It reflects the importance of connection with loved ones, especially with your mother in the dream.
5. The Books and Chess Pieces: Finding books in your grandmother's house may represent wisdom, heritage, or memories. The specific mention of a Harry Potter book with a Miraculous Ladybug drawing could symbolize a blend of fantasy and childhood wonder, indicating your imaginative side. The moonstone and labradorite chess pieces suggest a strategic approach to your emotions and decisions, as these stones are often associated with intuition and spiritual insight.
6. The School and Pyramids: The renewed school signifies growth and new opportunities in your educational or personal life. The burning may represent anxiety or fear of change. The proximity of the school to the pyramids suggests a connection to history, stability, and ancient wisdom. It may also indicate the importance of building a strong foundation for your future.

Overall, your dreams reflect themes of exploration, connection with family, personal growth, and a longing for understanding your emotions and experiences. Consider how these themes resonate with your current life situation. It might be helpful to engage in creative activities or reflection to further explore these feelings.
