A bird caught in a room, net or tangle stands for a wish or a voice that feels hemmed in. Dream books link it to situations where you feel unable to act freely.
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.
