You live in a house made of sweets; you are
walking in the clouds; you don't have to go to school tomorrow. How could all
of these a {#blank#}1{#/blank#} things happen? In your dreams.
A dream is quite a lot of pictures ideas
and fellings playing in the mind during sleep. Humans spend one third of life
sleeping and six years dreaming. A person usually has three to five dreams a
night, a {#blank#}2{#/blank#} one
may not remember his or her dreams.
Many dreams, at least the ones we remember,
are strange and interesting. That's why most people believe that dreams must
have some deep meanings or important m {#blank#}3{#/blank#} . But
people in different cultures have different understandings of the same dream. For
example, when dreaming of fire, Chinese people think of money, Japanese may say
it is "trouble". For people in the West, a dream of fire means something
new is coming.
Scientists have very different opinions
about the deep meaning of dreams. Some believe that a dream is only an ordinary
part of sleep and doesn't tell us anything. Other scientists think that dreams
directly show what people think of these days. Dreams are like a window into
one's wish and fears. For example, if you are very nervous about an exam, you
may see someone strange r {#blank#}4{#/blank#} after you in your dream.
Technology also helps us to know more about
dreams. In some films, people can enter others' minds while they are dreaming. Well
now, out of the dreams, we can really do it, too. Scientists can now r {#blank#}5{#/blank#} people's
dream by scanning(扫描)their brain activity
during sleep. Would you let scientists look into your dreams?
