The hearth is one of the oldest symbols of home, family and gathering. Dream books read a lit fireplace as belonging and an empty one as a longing for warmth.
Has this come up in your dreams before? What was going on in your life then?
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.
