An electric blanket gives warmth on demand, so tradition reads it as comfort you can rely on — or comfort that comes from outside rather than from the people around you.

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.
