A convulsion is like when your body gets a little mixed up and starts moving in a way you can’t control, kind of like when a toy robot starts shaking because its batteries are running out. Your brain is sending too many signals all at once, like a traffic jam of thoughts, and your muscles start to move on their own. It can be a bit like a surprise dance that you didn’t plan.
Think of your body as a computer. Sometimes, a computer can freeze or glitch, and it doesn’t do what you want it to. A convulsion is a bit like that for your body. Your brain is the computer’s control center, and when it gets too many signals, it might make your arms or legs move all by themselves, just like when a computer mouse moves without you touching it.
Or, imagine if your body is like a garden hose. When the water flows smoothly, everything is calm and normal. But if there’s a kink in the hose, the water might spray everywhere unexpectedly. A convulsion is like that unexpected spray, where your body is trying to figure out what to do next.
