A leaflet pressed into your hand stands for a message from outside — an offer, a warning or an invitation. Dream books read whether you keep it or toss it as how open you are to new ideas.
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.
