The harpy, half woman and half bird, is read as something that snatches away what you were about to enjoy. Dream tradition links it to nagging voices, sudden losses of peace or criticism that swoops in.
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.
