Innocence in a dream is read as purity, openness and a return to trust. Being declared innocent mirrors relief from guilt you may have been carrying.

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.
