An animal that feels like a guide is read as a quality you are being reminded of — courage, patience, cunning. Many traditions treat such a dream with respect, as a meeting with your own strengths.
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.
