Feelings that flip from one extreme to the other are read as an inner climate that has not settled. Dream books see it as emotions catching up with one another.
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.
