The bathroom scale is read as self-assessment and the pressure of being measured. In dream tradition it reflects concern about how you see yourself, not a verdict on your body.

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.
