I remember this past Spring when I was at a hotel for a week with a roommate for a "class" I was taking and I hadn't ever met this woman before this class. One morning she was smiling and said, "I'm sure your husband has told you this. . ." and I was puzzled and guessed, "that I snore?" and she said no, that I talked in my sleep! I'd never done that and had trouble believing it. I asked her what I'd said and she said I was mumbling the "speech" I had to give many times each day. It was an international diplomatic thing and I was representing Venezuela so was mumbling about "the delegation from Venezuela wishes to. . .through the Chair" the formal opening I had to make everytime I wanted to speak. Of course, I NEVER wanted to speak :-) but since I was representing good old Hugo Chavez, I had to speak often, loudly, and confidently. So, I was obviously in overdrive, my own "Self" versus my supposed-to-be Venezuelan self conflicting badly.
