Disability in a dream is read as meeting a limit and finding another way around it. Tradition sees it as adaptation and resourcefulness, and sometimes as feeling held back in some area of waking life.

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.
