A wiretap is read as privacy breached, private words overheard. Dream books link it to suspicion and to worry that what you say is being used against you.
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.
