Okay kiddo, so you know how movies and TV shows have actors pretend to do things like fight or get hurt? Well, there are some videos on the internet that are pretending like that too, but they can be VERY scary and not appropriate for kids to watch.
One type of video you might hear about is called a beheading video. This is when someone pretends to cut off someone else's head with a big knife. It's important to know that this is NOT real - it's just a pretend video made to scare people or make them think something bad is happening when it is not.
Watching these types of videos can be very upsetting and scary, so it's important to always check with your parents or another trusted adult before watching anything online. And if you come across something that makes you uncomfortable or scared, always remember to tell an adult right away so they can help you stay safe.
