Poison is read symbolically as something harmful taken in slowly — a toxic relationship, a bitter thought, words that linger. Dream books treat it as a cue to notice what is quietly wearing you down, not as a literal threat.
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.
