Smudging with smoke from sacred herbs is read as clearing a space of heavy feelings. In a dream it points to a wish to cleanse a mood, a room or a relationship and begin fresh.

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.
