I am not sure but do think that you did a soul retrieval. You probably helped with your friend's spiritual progress. I hope she gets through and resolves what brought her there and can move on to healing.
I would say the projector is symbolic, I'm not sure how to interpret- from the simplest 'astral projection is something that is costing you' (heavy and you owe money for it) to the more psychological 'projecting your unwanted characteristics unto others is also not good or pleasant or works for you' type of message. Only you can figure that one out.
