I had a dream, but it was hazy and I don't remember it very clearly. However, I do remember one thing: I seemed to have encountered some trouble. I was riding a horse into a valley, and it was pitch black… But the problem is, I've never ridden a horse in real life. How can I learn a skill in a dream that I don't know in real life? Some people say you can find anything in dreams, and it seems they're right.
