A competition is read as ambition, comparison and the urge to prove yourself. Dream books ask who the rival was, since it is often a standard you hold yourself to.
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.
