An assassination is read as a sudden, targeted ending: an influence, a role or an authority removed at a stroke. Dream books also link it to feeling undermined by someone you did not see coming.
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.
