So in my dream, I was playing piano, and even though in real life I am a guitar player, I am definitely not a pianist. Though in the dream, I was able to play piano pretty well. My left hand was playing one thing, and I had complete independence with my right hand playing the melody. I remember being very impressed with myself in the dream. Like wow, I'm pretty good and I'm not even trying very hard. Lol. I wish that would have triggered me into lucidity but it didn't. If I ever become lucid again in a dream, I'm going to try to play the piano and see if I can do it.
