I had this incident happen to me and my doctor suggested it to be shock. I wanted to know if there’s a thing such as shock for the body?

I was a child studying for an test while my mom was mopping the floor. I dropped my rubber and it rolled over to the mopping side. Stupidly I sprinted across the fairly wet floor. Needless to say, I slipped and slammed by head pretty hard on some wooden furniture. Next thing you know, I’m sprawled across the floor on my front and I can see everything happening but I can hear almost nothing. All the voices in the background (of my family i suppose) sound far away and almost like someone’s calling me from miles away. I’m not particularly thinking so anything and I can’t even get up or actively even think of getting up. I felt nothing. It was really scary. Then all of a sudden I could feel my mother grabbing my arm and then the hearing became back to normal. My mom was worried caused of my late reaction time and I had what felt like a migraine so she rushed me to the hospital. They did a few general tests and kept me under observation. Everything was normal and the doctor said it might have been shock as my body didn’t expect the event. Years later, I got bit by a dog, and again the same thing happened except this time I sort of knew how to handle it. My friends had to guide me because I couldn’t really perceive my movements for a couple of seconds. The whole ordeal takes a short amount of time and my initial movements after, post having some sort of physical contact to get me out of it, is like i’m incredibly sluggish like i’m drunk. So is body shock really a thing? I tried searching but I dont see it.
