I have never met myself AS myself in a dream, though I have come close twice. Once was simply when I was done dreaming and was ready to come back to my body, as it were. I got to my bedroom door, and I couldn't will myself to go any farther. The second time I had found within my dream a ring to which I was rather attatched, but which I had lost in real life. So I planned to put it where I used to keep it on the dresser next to my bed. I was aware that I was sleeping and that it wouldn't be there the next morning, but I figured that it would be nice to know that it would be there in essence. Odd thing that it happened to be named Gavanlediolor (literally, "Ring of Dreams"). I got half-way across my room -- and this took ENOURMOUS amounts of mental and metaphysical effort, if you would -- before I fell to one side in the dense pressure of the air around me and was forced awake. That dream left me EXHAUSTED -- but oddly contented. I would not reccommend such endeavors, ar any rate.

I have also met my three-year-old self (when I was ten, and not in an LD), an several Aspects of my Self, inluding my animus (who apparently is a Hindu from India) and my alter-ego.

Of course, I see myself much of the time in my dreams, because I often have my dreams in third-person. But that is different then actually MEETING myself in a dream.
