An altar server is read as dutiful assistance and childhood memories of ritual. The dream may also reflect a supporting role, standing close to authority while still learning.
Does the traditional reading fit your dream, or did it mean something else to you?
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.
