A parliament is many voices arguing toward one decision. Dream books read it as your own inner debate, where different wishes and duties each try to win the vote.
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.
