A sleigh gliding over snow is read as moving easily through a cold or difficult season. It stands for festive anticipation, and for being carried along by a joy you did not have to work 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.
