Earplugs are read as the wish to shut out noise, criticism or demands. Dream books also see them as refusing to hear something you would rather avoid.
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.
