A dead bird is not read literally; tradition sees it as a hope or plan that has run its course, or a freedom that feels lost for now. Like most endings in dreams, it is usually taken as the close of one chapter rather than a warning. Finding a dead bird on your path is read as noticing a loss you had not admitted. A dead bird at the window is taken as a message that went unheard or an idea that never took off. Burying it is read as gently letting something go, and a bird that revives as hope returning. It can help to ask which wish of yours has gone quiet, and whether it needs mourning or a second try.

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.
