A walkie-talkie is read as taking turns to speak and listen, and staying in touch at a distance. Dream books see static on the line as communication breaking down.
Where in your waking life have you met something like this lately?
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.
