Floating outside your own body is read as seeing your life from a distance. Dream books see it as detachment, perspective, or a wish to step away from pressure for a while.
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.
