A park is nature arranged for rest, and is traditionally read as a calm space in the middle of a busy life. Walking there can stand for recovery; a dark or empty park for loneliness.
Does the traditional reading fit your dream, or did it mean something else to you?
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.
