A paperweight keeps loose pages from blowing away, so it stands for the need to hold scattered thoughts or plans in place. Dream books also read it as something small that keeps you grounded.

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.
