The yew grows in old churchyards and lives for centuries, so tradition reads it as continuity between endings and beginnings. It stands for remembrance and renewal rather than for a loss to come.
Has this come up in your dreams before? What was going on in your life then?
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.
