I've "seen" many Talmidei Chachamim not saying the Ribbono shel Olams following each bracha of Birkas Kohanim. At least, I hear them chanting with the Kohanim from start to finish. Are these tefilos said only if you have a specific dream that you are worried about?
And, if I already said it, why say it twice? (Unless once I identify that I had a dream, I take advantage. I do recall that the Siddur Ishei Yisrael ("the Gra's siddur") had 3 Ribbonos: the first ends v'yishmereini for the yishmerecha bracha, then v'choneini for vichuneka, the 3rd concludes with visirtzeini. So perhaps we have a postsurgical version after the yehi ratzon was added?)
