Well, Carrie White is indeed based on a true story. King often draws from the real world to create his terrifying tales. There were likely instances of bullying and outcast situations that he heard about or witnessed, which he then used as a foundation for Carrie's story. He then built on this with his own brand of horror and the supernatural to create the iconic character we know.
Carrie White is not based on real events. It's a product of the author's imagination. The story was crafted to explore certain themes and emotions rather than being drawn from actual happenings.
One common theme is redemption. Since Carrie's story in the original is so tragic, many fanfics try to give her a chance at redemption, like making amends for the destruction she caused.
There might be a 'carrie white fanfiction' where Carrie travels to a different dimension. In this new world, her powers are seen as a gift and she becomes a hero instead of a feared outcast. She uses her powers to fight off evil forces and protect the innocent people there.
Well, the 'Carrie White' story has roots in real experiences. Stephen King is known for taking real - life concepts and turning them into horror. The idea of a misfit like Carrie being bullied and having a difficult life was something that could happen in reality. The telekinetic powers were added for the horror aspect, but the underlying story of an outcast is very much related to real - life situations of those who are bullied and marginalized in society.
One key event is Carrie's humiliation at the prom. She was doused with pig's blood in front of everyone. Another is her discovery of her telekinetic powers.
One challenge is maintaining Carrie's character traits. She has a complex personality due to her experiences, so when crossing her over, it's important to keep that intact. For example, her shyness and the power she holds. Another challenge is making the crossover believable. If she crosses into a very different universe like 'Star Trek', the writer has to find a logical way for her to fit in. And finally, there's the challenge of pleasing the fans of both the original Carrie White story and the universe she's being crossed into.
