Like teeth falling out, fingers coming loose are read as anxiety about losing control or competence. Dream books treat it as a picture of strain and helplessness rather than anything bodily.
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.
