I definitely do. I took a belly dancing course and the mirror messed me up. Once I started focussing on the teacher's back, rather than the mirror, I did better. Still, when she would say "do a forward figure 8" (or whatever move we were doing) while facing me and doing the move, I would do a backward figure 8, etc. Group dancing was awkward until I memorized just what I was supposed to do, and where I was supposed to be at which point in the music, and ignored the other girls.
Just this past weekend I took a salsa dancing lesson. It was also the first time in my life that I had actually danced with someone. I just couldn't keep up with the left-right commands and the mirroring of the partner's moves. I don't know what the poor guy thought about me, but I was just hysterically laughing because I was really really bad at the dance. I have a feeling I had better stick with the belly dancing - its more my style, I can do it without having a partner, and I get to lead...
