Seabirds live between the open water and the shore, so dream books read them as thoughts that move between deep feeling and everyday ground. Their cries over the waves are often linked to longing for distance or for news from far away.

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.
