Taking in and casting out is read as a cycle of craving and rejection — wanting something and then wanting to be rid of it. Dream books see it as an inner tug of war.
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.
