"Dreams (梦 ) may be more important than sleep. We all need to dream," some scientists say.
     Dreams take up about one quarter of our {#blank#}1{#/blank#} time. People have several {#blank#}2{#/blank#} each night. Dreams are like short films. They are usually in color. Some dreams are {#blank#}3{#/blank#}  old films. They come to us over and over {#blank#}4{#/blank#} . That may be because the dreamer is worrying about something. Dreaming may be a way of trying to find an answer.
    Some people get new ideas{#blank#}5{#/blank#}  their work from dreams. They may have been {#blank#}6{#/blank#}  about their work all day. These thoughts can carry over into dreams.
    Sometimes, we {#blank#}7{#/blank#}  with a good feeling from a dream. But often we can't remember the dream. Dreams can disappear (消失) {#blank#}8{#/blank#} from memory (记忆).
    Too much dreaming can be harmful (有害的). The {#blank#}9{#/blank#}  we sleep, the longer we dream. The mind is hard at work when we dream. That is {#blank#}10{#/blank#} we may have a long sleep and still wake up tired.
