Blue is read as calm, truth and distance — the colour of sky and deep water. It traditionally stands for peace of mind, and sometimes for longing. Light blue points to openness and relief, while deep, dark blue is read as depth of feeling or melancholy. A blue door or room suggests a place of rest, and blue clothing a wish to be trusted or to keep things calm. Being surrounded by blue water is taken as being held by emotion. Cold, icy blue is read as distance in a relationship.
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.
