A memory card is read as stored experiences and the past captured in a small space. Tradition links a full card to a mind overloaded with memories, and a lost one to fear of forgetting.

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.
