A painkiller is read as dulling a hurt rather than addressing it. Dream books see the wish for quick relief, and a gentle question about what the pain itself is pointing to.
Where in your waking life have you met something like this lately?
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.
