I'm still figuring out where each part of me ends and another one begins, and I'm still figuring out what to make of the gaps in my memory (which as far as I know are not frequent anymore) and of confusing reports from other people about things I supposedly have said or done. So I don't know yet what kinds of memories, objective or emotional, are still waiting to be recovered (including possible self-image(s)).
I remember a dream I had when I was little, where I was looking at myself from the ceiling, and I saw myself waking up. Except I didn't look at all like my (physical) self, and somehow I knew my name was Daniel (which doesn't sound familiar to me). I remember "my" physical features in that dream very well. Whether that kid in the dream survived as a part of me that I'm not in touch with, I simply don't know. Though I remember the dream vividly to this day, which is unusual. I can't feel any emotions about it anymore, but I remember I used to take comfort in the memory.
I'm generally only good with "abstract imagination" on one hand, and "concrete recollection" on the other. I don't recognize my physical image as my own, and I have no well-defined image for any of my parts. Any self-image I have is dependent on "recognizing myself" in pictures I see, like the ones I use as avatars here on PF (usually singers and musicians, and sometimes fictional characters).
(For future reference, the image below is my current avatar: Faith, from Mirror's Edge).
