Odd, but considering how much I enjoy cycling, I don't think I've ever dreamed of riding a bike. Maybe the real thing is good enough and there are no unresolved issues. Assuming that's what dreams are for. I'm not sure experts have ever agreed on the purpose of dreams.
However, I play piano well... in my dreams. Never even attempted it in real life. I was a mediocre guitar player but rarely dream of that.
I seem to spend a lot of time flying or at least gliding just above ground level in my dreams. Kinda fun.
Most of my dreams are so mundane I can hardly remember them and occasionally mistake them for real events, until I wake up and think about it.
