A cannibal is read symbolically as being consumed by others — their needs, demands or energy. Dream books also link it to taking in the qualities of someone else.
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.
