Being replaced by someone else is read as insecurity about your place — in love, work or a family. Dream books link it to fear of being forgotten or easily exchanged.
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.
