The great wildebeest migration makes this animal a symbol of a long collective journey. Dream books read it as being carried along by a crowd, or as the drive to keep moving toward greener ground.
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.
