One interesting 'Harry Potter Nightmares' fanfiction could be one where Harry has nightmares about Voldemort coming back in a more terrifying way than in the original books. Maybe in his nightmares, Voldemort has powers that are even more extreme and he's able to control the minds of everyone in Hogwarts at once.
Well, it could be that Harry Potter in fanfiction controls nightmares by tapping into his inner strength. Since he has faced so many dark and terrifying things in his life, he might have developed a mental resilience. He could use this mental strength to enter the dream world consciously and change the nightmare scenarios, just like he faces his real - life enemies.
There's a possible 'Harry Potter Nightmares' fanfic where Harry dreams of Hogwarts being destroyed by an unknown, unbeatable dark magic. The halls are filled with the screams of his friends and teachers, and he is powerless to stop it. Another idea for a fanfic could be Harry having nightmares about the Dementors multiplying out of control and draining the happiness from the entire wizarding world. A third interesting fanfic could be Harry having nightmares about the prophecy being wrong and he is actually the cause of all the dark events in the wizarding world.
You can start by looking on fanfic platforms like Archive of Our Own (AO3). It has a large collection of fanfics, and you can search specifically for 'Harry Potter Nightmares' in the search bar. Another option is Fanfiction.net. It has been around for a long time and also has a good number of Harry Potter - related fanfics. Just use their search function to find the ones related to nightmares.
One possible plot could be that Gordon Ramsay visits the Hogwarts kitchens. The house - elves are used to their traditional ways of cooking and are resistant to change. Ramsay tries to introduce modern muggle cooking techniques to them. For example, he might show them how to make a proper steak instead of just serving up mystery meat stew all the time. There could be chaos as the house - elves initially reject his ideas, but eventually come around when they see the students enjoying the new food.
These fanfictions can introduce new plot elements. If a character has a nightmare about a secret chamber in Hogwarts that no one knew about, it can lead to a whole new adventure. It expands the world of Harry Potter and keeps readers interested. It also allows for different interpretations of the magic system. Maybe in a nightmare, magic behaves in a strange way, which can then be explored in the fanfiction.
One way could be through meditation. In fanfiction, Harry might have learned some advanced meditation techniques from the Hogwarts library or from a mysterious wizard. By meditating, he can clear his mind and create a mental shield against nightmares.
The 'Days of Futures Past Novel' could potentially be a story that delves into the various aspects of a future world. It might have themes like time travel where characters go back and forth in the days of the future past. Maybe it shows the consequences of actions taken in different future timelines and how they all interconnect. It could also be about a group of people trying to survive or thrive in a post - apocalyptic future that has a past of its own, filled with events that led to the current state of affairs.
Chef Ramsay would be the central figure. Then perhaps Hagrid could be a character. Hagrid is always dealing with magical creatures and he could provide some very interesting and unique ingredients for the kitchen. Also, Neville Longbottom could be there. He has a love for plants, and he could contribute by providing fresh magical herbs for cooking. And of course, the Hogwarts head chef, who would be resistant to change at first but gradually learn from Ramsay.
Perhaps in this fanfiction, the nightmares of Voldemort start to seep into the minds of the Hogwarts students. Harry has to figure out a way to stop these nightmares from spreading fear and chaos throughout the school. He might need to find a powerful spell or a magical object that can act as a shield against such dark mental invasions. This could involve a journey through the Forbidden Forest or exploring the hidden chambers of Hogwarts.
