The nagging fear of a stove left on is read as worry about something neglected that could get out of hand. Dream books link it to a sense of responsibility that does not switch off.

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.
