Students fall asleep easily in class. Why do they suddenly wake up in class and shake their legs?

Sleeping in class is something that many students have done. But students wake up suddenly in class and shake their legs. How come... Let me talk about my opinion!

When we are in class, if we don't pay attention to the teacher's lecture, we will be easily distracted and doze off at this time. At this time, you are likely to fall asleep in class! And you will sleep soundly in class, but suddenly wake up and shake your legs. The main thing is that you remember this is a class when you sleep, for fear that the teacher will suddenly call you. When you wake up, you will think that your teacher or classmates are calling your name. Then you will shake your legs! Wake up and shake your legs. Many people will have this kind of experience, which is horrible.

I remember falling asleep in class when I was studying, and I suddenly woke up soon. He also overturned the desk and made the whole class laugh. As a student, I think we should listen carefully in class. The classroom is where we teach, not where we sleep. Sleeping in class is also particularly disrespectful to teachers, and teachers must especially hate people who sleep in class! So when we study, we must ensure enough sleep, don't stay up late at night, and leave some time to sleep at noon. In intense study, dozing off is inevitable, but it can be restrained. As long as you have good habits, you won't sleep in class the next day!

I wake up suddenly in class and shake my legs, mainly because I am still afraid, thinking that someone is calling you, and I am a little scared. Waking up suddenly will increase your inner fear. So I will shake my legs when I suddenly wake up!

The above is just my personal opinion, of course, there will be more authoritative answers. But I think we should listen carefully and concentrate on the teacher in class. This can also greatly avoid dozing off, and think more about problems in class, so you won't fall asleep!
