The castle is a classic symbol of protection and the fortified self. Tradition reads it as strength and ideals, and its walls as the defences you keep around what you value. Living in a castle points to a wish for security or recognition, while being locked inside suggests isolation. A castle under attack is read as feeling your boundaries challenged. A ruined castle is linked to old ambitions or defences that no longer serve.
When this appeared in your dream, what were you feeling?
My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
