When you sleep, can you know that you are dreaming? If yes, then you are having a lucid dream (清醒梦). It is hard for most people to know it. Only some people are able to know 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 are key to helping people have lucid dreams.
First, people train themselves to figure out (弄明白) that they are dreaming or they are not. People can practice a way 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 situation while sleeping. But in their dreams, the time on the clock may change very quickly. So people know they are dreaming.
Another way 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 begin rapid eye movement (REM,快速眼球运动) sleep. In REM sleep, people can know their dreams.
Scientists found that those who used these ways had a 17% success to have lucid dreams. This was far higher than if they did nothing. And in a lucid dream, people might study a hobby and then become better at that hobby in real life.
