An orphanage is read symbolically as feeling unsupported or left to manage alone. Dream tradition also sees it as compassion for the parts of yourself that once needed more care.
Has this come up in your dreams before? What was going on in your life then?
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.
