A jump is traditionally a leap of faith — a sudden move across a gap. Dream books read a clean jump as courage, and a hesitant one as doubt before a decision.

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.
