The meaning of adopt / adoption in dream | Dream Interpretation
To dream that you or others are adopting a child indicates that you are taking on something new and different. Ask yourself what is missing in your life that would make you happy.
If you dream that you are adopted (and you aren’t in real life), you are feeling out of place in some real-life situation. You may also suspect that those closest to you have been lying to you.
If you dream of giving up a baby for adoption, there is some aspect of yourself or your personal life that is changing, and you are feeling a sense of loss. You may have made a decision you can’t take back, or be sad or anxious about moving on to a new stage. You may also be having trouble making a new personal goal or project happen. Also see “Baby”
