A bud is something about to open, so it is read as promise, potential and a beginning not yet shown. Dream books link it to youth and to feelings just starting to form.
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.
