Being shorter than everyone around you is read as feeling overlooked or out of reach of what others have. Dream books also see it as a reminder that worth is not measured in height.
When this appeared in your dream, what were you feeling?
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.
