The yeti roams snowy mountains far from people, and dream books read it as isolation and a mystery at the edge of what you know. It can stand for a challenge that only appears on the high, cold path.
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.
