Haze softens everything at a distance, so it stands for vague feelings, half-memories and a lack of sharp focus. Dream books read it as a mind that is tired or not yet ready to see clearly.

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.
