Yes, there is. In the 'Hatchet' movie series, Victor Crowley is a fictional character, but his story is inspired by various horror tropes and legends. He's a deformed and vengeful killer in a Louisiana swamp setting. The movies create a backstory for him that involves a tragic accident and a curse, which gives him his murderous nature.
The main element is the setting. It's set in a Louisiana swamp, which is a classic spooky location. Another is his tragic origin. He had an accident that led to his death and disfigurement.
Victor Creel's real story is centered around a tragic event in his family's home. He was the only survivor, but was accused of the murders. In the context of Stranger Things, we learn that there's a connection to the Upside Down. His mind was manipulated by Vecna. Victor's story is not just about the murders he was wrongly accused of, but also about his struggle with the truth. He was in a state of confusion, having seen things that defied normal understanding. His time in the asylum was filled with torment as he tried to come to terms with what had really occurred, all while being under the influence of Vecna's power, which had a major impact on his life and the events that unfolded.
Well, if we consider the Victor Creel story as it exists in 'Stranger Things', it's true within the framework of the show. The show has its own set of rules and backstories, and Victor Creel's story is an important part of that. However, outside of the show, it has no basis in real - world events. It's a fictional tale crafted to add mystery and horror to the Stranger Things storyline.
