A shot glass holds a small amount meant to be taken all at once, so it is read as impulse, intensity and decisions made in a single quick move.
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.
