A gold rush stands for a feverish chase after quick reward among a crowd doing the same. Dream books read it as ambition and hope, and the question of what is left behind in the stampede.

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.
