The peryton, a winged stag that casts a human shadow, is traditionally read as an identity out of place. Dream books link it to feeling that your outward self and inner self have drifted apart.
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.
