Hearing a weather forecast in a dream is read as the mind trying to prepare for what lies ahead. Tradition sees it as a mood of anticipation, calm or uneasy, rather than as a message about any real event.
Where in your waking life have you met something like this lately?
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.
