Cables carry power and signal between things, so they are read as the ties that keep you connected. A tangle of cords stands for relationships or obligations that have become knotted.

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.
