Elephantiasis is read as something swelling out of proportion. Dream books link it to a problem or a feeling that has grown too large to carry easily, and to feeling self-conscious about being seen.

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.
