A castle in a dream may be symbolic of the “cavern of the heart.” It represents the home of the human spirit (yours) and the natural self. Dreams with castles in them may come from deeper levels of the unconscious, or the collective unconscious. They may represent spiritual transcendence and the mysterious and intangible force that seems to quietly, but firmly, direct our lives. A castle in a dream may also represent feelings of security, protection, isolation or remoteness. You may have a castle dream when you have realized a desire or accomplished a goal. Darkened castles may be symbolic of unconscious or unfocused desires, at times, black castles represent our failures and white, or lighted castles, symbolize achievement and awareness.
