A shapeshifter is read as instability — a person, situation or self that will not keep one form. Dream tradition links it both to adaptability and to the unease of not knowing what is real.
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.
