Today,I want to tell you a true story.It happened 3 years ago.At midnight,I was surfing on the Internet.After time,I was a little tired.so I went to bed.I had just lain down,I saw agreat many of lines that looked like black and white on the top wall.It looked like abad television. Just then ,I found,I couldn't moved.It was very terrible.
My heart was very fear as a poor child. But after a moment,I could moved.I knew.This was "ghost burden"that people often discussion.
大意是：今天,我想跟你讲一个真实的故事,它发生在3年前,半夜的时候我正在上网,过了一会,我感觉有点累,我去了床上,我刚刚躺下,我看到了房顶有很多黑色和白色的线条,它看起来像一个坏掉的电视机,就在这时,我发现我不能动了,这太糟糕了,我感觉我就像一个可怜的小孩,但是过了一会,我发现我能动了,我知道了,这就是人们经常讨论的鬼压身.
