Friendship is also a theme. His friends may play different roles in his learning process. Some might support him unconditionally, while others might not understand what he's going through, which can create interesting relationship dynamics within the fanfiction.
In this type of fanfiction, the relationship between Harry and Snape can be re - imagined. Snape was Harry's teacher for Occlumency in the books, but often their interactions were tense. Fanfic writers may change this dynamic. They could have Snape be more patient or Harry be more receptive, which would lead to a different kind of mentorship and a new understanding between them.
Harry Potter himself is, of course, the central character. Snape is also very common as he is Harry's teacher in occlumency in the original books. Hermione and Ron often make appearances as well, as Harry's best friends. They might be involved in helping Harry learn or just be there for moral support.
One common theme is self - discovery. As Harry learns light magic, he often discovers new aspects of himself and his potential. Another theme is the power of good over evil. Light magic is usually depicted as a force for good, so it's about using it to combat the dark forces in the wizarding world.
Some fanfictions might focus on Harry learning occlumency in a more collaborative way with his friends. For example, Hermione could be helping him study the theory behind it while Ron provides moral support. This can add a new dynamic to the story. Also, there could be a plot point where Harry discovers some hidden secrets about occlumency that are not mentioned in the original books, which then leads him on a new adventure to understand it better.
Snape is often a central character as he was the one teaching Occlumency in the original series. Harry Potter also frequently appears since he was the one receiving the lessons. Hermione might be included as well, as she is always eager to learn new magic and could be interested in Occlumency.
Overcoming limitations is also a theme. Since wandless magic is not the norm in the wizarding world as presented in the original books, Harry has to break through the traditional thinking. He has to deal with the doubts of others and his own insecurities. In some fanfics, he even has to face opposition from the Ministry of Magic who are wary of this unregulated form of magic.
The theme of self - discovery for Ginny is often seen. As she delves deeper into the situation of Harry being a Horcrux, she might discover new aspects of herself, like her own strength in dealing with such a complex and dangerous situation. And there's also the theme of hope, that despite the seemingly impossible situation, there is always a way to save Harry and defeat Voldemort.
In Occlumency Lessons with Snape fanfiction, the theme of trust is very prominent. Harry doesn't trust Snape, and Snape has his own reasons not to fully trust Harry either. This lack of trust affects how the lessons progress. Also, the theme of self - discovery is common. Through these lessons, Harry learns more about his own mind and his capabilities. Additionally, the power dynamics between Snape and Harry, with Snape being the more experienced wizard, is a recurring theme that shapes the interactions during the lessons.
Characters with natural Occlumency in these fanfictions are usually depicted as having an edge in the magical world. They can be portrayed as being able to keep their thoughts and emotions hidden effortlessly, which makes them excellent spies or secret - keepers. In some fanfics, they are also shown as having a deeper understanding of the human mind and magic's connection to it because of their natural ability. This allows them to manipulate situations in ways that others can't. For instance, they might be able to sense when someone is trying to use Legilimency on them from a greater distance compared to those who have to learn Occlumency.
In fanfiction, Snape's teaching of Occlumency to Harry Potter often takes on different twists. Some fanfictions explore Snape's inner turmoil while teaching Harry. He has to balance his hatred for James Potter, Harry's father, with his loyalty to Dumbledore's plan. This makes the Occlumency lessons a complex and emotionally charged situation. Harry, on the other hand, struggles not only with learning the difficult skill but also with his distrust of Snape.
