Being poisoned is read as a harmful influence working on you from within — words, habits or a relationship that are slowly doing damage. Not knowing who poisoned you points to vague distrust, while a known poisoner suggests a specific person you feel wary of. Poisoning someone else is read as guilt, or as resentment you have not expressed openly. Finding an antidote is taken as recovery and clarity. It can help to notice what leaves you feeling worse each time you meet it.
Does the traditional reading fit your dream, or did it mean something else to you?
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.
