The heart stands for love, courage and what matters most. Tradition reads a dream about it as a question about what you truly feel. A beating heart points to vitality and strong emotion; a broken heart is linked to grief, disappointment or love that ended. Giving your heart to someone is read as trust and vulnerability; a heart in pain stands for emotional stress rather than any physical sign. A heart that stops in a dream is read as a pause in feeling, not a literal event. It can help to notice what in your days your heart is asking for.
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.
