Orphaned / Adopted / Fostered dream meaning is explained below using 1 different source. Each interpretation is shown with its source.
Interpretation 1 — Theresa Cheung
Another explanation of such dreams is that it is time for you to be more independent and self-reliant by moving away from your parents. When life forces you into permanently or temporarily losing your parents, either by death or by other circumstances such as foreign travel, you may experience dreams of being orphaned. The dream might not refer to your relationship with your family at all, but might be telling you that you are feeling abandoned, unloved, rejected and misunderstood by your partner, friends or colleagues in waking life.
If this is the case, the dream connects to feelings of belonging or not belonging in waking life.
If you are looking after an orphan in your dream, you are attempting to heal that part of you that feels unloved.
