A nest on the ground is read as a disruption to your sense of home or security. Dream books also see it as the chance to rebuild somewhere more stable.
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.
