A bird that cannot fly is traditionally read as strength that stays on the ground — someone who has given up one freedom and found another. It can also stand for a feeling of being held back from rising.

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.
