Chaos in a dream is read as feeling overwhelmed by disorder in some part of life. Old traditions also see it as the raw material from which new order forms.
When this appeared in your dream, what were you feeling?
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.
