Your description of what your hands looked like exactly match what happened with me earlier this week. Very interesting to know that someone else's experiences are similar to mine. The only thing I remember about my dream is that I was in a dimly lit space. For some reason, I thought to look at my hands and had the same imiage of them as you did. I felt like I was struggling to do it, like my hands did not want to be seen. I put my arms back down, and tried again. I couldn't quite get to the point where I realized I was dreaming, though.
