How does Harry feel when he uses a ritual to travel to an au fanfiction?

Well, he might find himself in a completely different world with alternate versions of the characters he knows. For example, the relationships between characters could be reversed or changed in unexpected ways. Maybe he'll see a version of his best friend as an enemy or a character who was once minor become a central figure.

Well, in many Harry Potter AU fanfictions, travel to an alternate universe can happen due to a disruption in time. If a time - turner is misused or there's a major magical event that messes with the time - space continuum, it can lead to an AU. Also, some fanfictions depict that a character's strong emotions and desires can trigger a journey to an AU. Say a character has a deep longing to see how things could have been different, and their magic responds by sending them to an AU. It's all very creative and varies from one fanfiction to another.

He might feel a bit self - conscious at first. After all, it's something different from what he's used to.

Vernon could be quite curious. He'll be eager to read what others have come up with. There might be new ideas, different takes on his character or his world that he hadn't thought of before. So he's probably excited to explore these new interpretations.

He may feel a bit weird. Fanfiction can be so different from his real self. He might not like some of the wild ideas people have about him.

He probably feels extremely hurt and confused. Betrayal by friends is a very painful experience, and Bell might question his own judgment in trusting them in the first place.

Yes, often it does. Fanfiction can offer new perspectives on the beloved Harry Potter world. When a writer expands on a minor character's backstory in an interesting way, it can be really satisfying to read.

He might feel relaxed. Reading a story can be a great way to unwind.

It could become very close and trusting. They'd know each other inside out and have a deep bond from childhood.

Well, in most fanfics, it might involve complex incantations and rare magical ingredients. Maybe something like a special potion made from enchanted herbs and a spell cast under a full moon. But it's all just fan - created ideas and not part of the official Potter lore.
