Are you all alone? Do you have a parent or guardian with you, or any other adult supervision? If the answer is "no" then you're in the exact same shoes as the characters in "A Pup Named Scooby-Doo". If it's beginning to dawn on you that maybe you can't be held responsible for your own safety then, well, this was a weird time to realize that.
The Scooby Dudes are tackling an episode that made them feel strange. And not like their bodies were changing, but more like they weren't sure what was real and secure in the world anymore. Basically this was a truly surreal episode to recap and they try to keep, and succeed in keeping, things fun. But things also got pretty dark.
