Losing an arm or leg is read as losing a capacity — to act, to reach, to move ahead. Dream books ask what in your life feels as if it has been cut off from you.
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.
