A hot spring is warmth rising from deep within the earth, so tradition reads it as comfort, healing rest and emotional warmth. Bathing in one points to a wish to be soothed and restored.
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.
