4 Read the passage and choose the answer which best completes each sentence (1) 1)~(4). We all know that any person has a dream while they are sleeping. We also know that it is difficult to remember dreams after we wake up. Most dreams are soon forgotten and they disappear like small bubbles in water. In addition, they often cannot be remembered at all after they are forgotten. Even if you can remember a dream soon after you wake up, perhaps you cannot remember it any more after getting out from your bed to make some coffee. Maybe you have had such an experience. Then, have you ever noticed that you were having a dream while you were sleeping? / Some people have had such an experience. It is called a lucid dream, and some scientists in the world do research on it. Actually, there are even research groups which focus on it. Why do they do research on lucid dreams? For one thing, there may be advantages for us. We will be able to avoid nightmares and make our dreams happier or more exciting if we can notice we are having dreams and we can control them like a pilot. Today, scientists do not know enough about lucid dreams and how to control them, so there are still many things to be done in the research. But it may be possible for everyone to have lucid dreams if science in the area improves more. Actually, that is one of goals that some scientists are trying to reach. According to a survey, over 75% of the respondents answered that they experienced a lucid dream at least once in their lives. Also, many reports about lucid dream experiences were given in history. We can find early reports on them in books from ancient cultures. For example, an ancient Greek doctor already tried to use lucid dreams as a kind of therapy over two thousand years ago. And controlling our dreams in our own ways was one of the important topics among early Buddhists in Asia.
