No. Disney did not make Pulp Fiction. Pulp Fiction is a Quentin Tarantino movie and is known for its edgy, violent, and adult - themed content which is not in line with Disney's typical family - friendly image.
The production of 'Solo: A Star Wars Story' was indeed the work of Disney. They have the capabilities and the brand power to create such major Star Wars projects, and this was no exception. Disney's involvement ensured high production values and a connection to the broader Star Wars universe.
Most likely a mix of both. Some stories might have been made - up to add to the castle's allure. But who knows? There could be some truth to the strange experiences people claim to have had.
I think they are a bit of both. While it's likely that some elements of the stories have been exaggerated or fabricated, the fact that the same types of stories keep being told might suggest that there was something unusual about the castle that led to these tales. Maybe there were unexplained noises or strange sightings that people in the past couldn't understand, and so they attributed them to ghosts.
Some are likely made up for entertainment purposes. People love to create spooky tales about popular places like Disney. However, there could be some elements that are based on real, albeit misinterpreted, experiences. For example, an odd noise could be due to a mechanical issue but be exaggerated into a horror story.
It's probably a misunderstanding. Maybe someone is not familiar with the distinct styles and reputations of the two entities. Disney is so well - known for its family - friendly fare, and Pulp Fiction is so far from that, that it's a very odd association.
