Homesickness in a dream is read as missing a place where you felt you belonged. Dream books link it to a search for safety, roots and the people or habits that once made you feel at ease.
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.
