Hey there kiddo, so have you heard of a barghest? It's a creature from English folklore, kind of like a really big scary dog.
Now, the barghest is said to have black shaggy fur, glowing eyes, and huge teeth - definitely not a creature you want to meet in the dark! Some people even believe that seeing a barghest means that someone close to you might pass away soon.
But don't worry, because barghests are just stories meant to scare people. There's no real evidence that they actually exist. So you can rest easy knowing that you won't be running into one any time soon.
