阅读下面的短文，在思维导图中填入恰当的内容完成阅读摘记。
Did you have any interesting dreams last night? Do you know everyone dreams? But not everyone remembers their dreams. A person can usually have up to seven dreams a night, and each dream usually lasts from 10 to 40 minutes.
Why do we dream? Scientists believe that we dream to remember because dreams come from our memories and they tell us a lot about ourselves. They also help us learn from the past and even help us solve problems.
Different dreams mean differently to people. For example, if you dream about flying, you are probably quite happy. This is a good time in your life. You may feel that other people see you as a leader. And when you dream that you didn’t study for a test, it usually means you are worried about an important thing coming in your life.
