shock

the feeling of distress and disbelief that you have when something bad happens accidentally

his mother's death left him in a daze

surprise greatly; knock someone's socks off

I was floored when I heard that I was promoted

strike with disgust or revulsion

The scandalous behavior of this married woman shocked her friends

the violent interaction of individuals or groups entering into combat

the armies met in the shock of battle

a reflex response to the passage of electric current through the body

subjects received a small electric shock when they made the wrong response
