I did that too, actually, and interestingly enough, a lot of my stories had to do with "saving" the very mother figures I wished would save me. I sometimes imagined saving their lives, or sometimes I imagined that they'd been through things I'd been through too, and they were really able to understand me because their parents had hurt them too, and that somehow I was able to heal them just as I wished they would be able to heal me. It's actually funny to think about that - I imagined in equal parts them saving me and me saving them. I was very big on this hurt/comfort theme. Ever since I was maybe three or four, maybe even younger, I always was.
