A boat tipping over is read as a sudden upset that turns things upside down. Dream books link it to feelings that overwhelmed a plan — and to the scramble to right yourself.

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.
