In what ways does Harry Potter fanfiction send him to another dimension?

In this fanfiction, Harry travels to a magical and mysterious dimension full of unknown creatures and challenges.

Well, a cool plot for 'Harry Potter in Another Dimension' fanfic could be that Harry discovers he has a twin in this other dimension. His twin has been raised by Voldemort and has a very different view of the wizarding world. Harry has to find a way to convince his twin to abandon Voldemort's ways. Or, what if in this dimension, the Sorting Hat can talk out loud all the time and gives very different sorting decisions? For example, it might put all the brave students in Slytherin and the cunning ones in Gryffindor. It would be really interesting to explore how the relationships between the houses change.

Perhaps a group of rogue time - traveling wizards. They come from a future in this dimension where the wizarding world has been destroyed, and they believe that changing the past (even if it means causing chaos) is the only way to save their future. They see Harry as a threat to their plans because he has a natural inclination to preserve the present order.
