The dream you described, taking place in your parents' flat in Brussels, is quite rich with layers of meaning and symbolism. Beginning with you and your parents engaging in a mundane conversation, it seems to reflect your current feelings about family dynamics and the routine nature of familial interactions. The sudden arrival of old acquaintances signifies a disruption in this routine, potentially representing unresolved issues or past relationships that have resurfaced in your subconscious.
The setting of the dream shifting to your old bedroom, where you find people from your past, suggests a return to your roots or a reflection on your past experiences. The two girls you encounter, one of whom is Sophia, may symbolize parts of your past that were not fully explored or understood at the time. The hidden room with the gigantic popcorn maker represents a discovery of something unexpected within yourself or your past that is now coming to light. The popcorn, which is typically associated with enjoyment and celebration, filling the room, could signify newfound joy or a realization that brings happiness.
The climax of the dream, where everyone celebrates the popcorn, coinciding with your real-life birthday, suggests a convergence of your subconscious and conscious mind in recognizing a significant moment or transition in your life. The return of the acquaintances to the living room and their subsequent disappearance when you re-enter signifies the fleeting nature of past relationships and the importance of moving forward.
Finally, the calm presence of your parents waiting for you at the dinner table juxtaposed with your fiancé calling your name indicates a balance between your past and present relationships. Your fiancé's voice pulling you back to reality might symbolize your current priorities and the future you are building together.
This dream is a profound exploration of your inner world, touching on themes of family, past relationships, personal growth, and celebration. It suggests a journey of self-discovery and the integration of your past experiences with your present and future aspirations.
