When you sleep, can you know that you are dreaming? If yes, then you are having a lucid dream (清醒梦). This is hard for most people to do. Only some people are able to do this. Now scientists have found ways to help more people to have lucid dreams, Live Science reported.
Denholm Aspy, from the University of Adelaide in Australia, found that certain skills (技巧) are key to helping people have lucid dreams.
First, people train themselves to figure out (搞清) whether （是否）they are dreaming or not. People can practice a skill for this in real life. For example, someone may look at a clock, look away, and then look back. The time should stay the same. Then, they might dream about this skill while sleeping. But in their dreams, the time on the clock may change very quickly. So people know they are dreaming.
Another skill is to wake up after five hours of sleep. Then, stay awake for a while. During this time, repeat (重复) the words, "The next time I'm dreaming, I will remember that I'm dreaming. " Then, go to bed again to enter rapid eye movement (REM，快速眼球运动) sleep. In REM sleep, people are more likely to be aware of（意识到） their dreams.
Scientists found that those who used these skills had a 17 percent success rate for having lucid dreams. This was far higher than if they did nothing.
In a lucid dream, people might study a hobby and then become better at that hobby in real life, according to Aspy. If you might learn to play the piano in a lucid dream, you might play the piano better in real life!
