Have you fell asleep during the day? I know your answer: yes.
However, sometimes you wake up with a sudden body movement?
Most people feel very embarrassed when they do that.
But, probably, not so many people know why it happens.
Now here is the reason
First of all, this reaction is called a “sleep start”.
It sounds little weird but there are five stages of sleeping
1. A doze
2. A light sleep
3. A deep sleep
4. A slow-wave sleep
5. REM sleep

The reaction happens when a person is distracted by something, when those stages are flopping over to the next stage. If the person is distracted, his body moves to wake up in unconsciousness, and it leads his body to the sudden muscle tension. That is why people sometimes wake up kicking the front person, or with a shock.
