One common theme is self - discovery. In many fictional travel stories, like 'The Alchemist', the protagonist goes on a journey and discovers more about themselves. Another theme is the encounter with the unknown. For example, in 'Frankenstein', Victor travels to the Arctic, and there he faces the unknown in the form of his creation. Also, friendship is often a theme. In 'The Lord of the Rings', Frodo's journey is made possible with the help of his friends.
One popular time travel fictional story is 'The Time Machine' by H.G. Wells. It tells the story of a scientist who travels far into the future and discovers a world divided into two species. Another is 'Back to the Future', a well - known movie trilogy. The main character, Marty McFly, travels through time in a DeLorean. 'Doctor Who' is also a great example. The Doctor, an alien Time Lord, travels through time and space in his TARDIS, having various adventures throughout history and the future.
There are many fictional travel stories. 'Peter Pan' is one, where Wendy and her brothers fly to Neverland with Peter Pan. It's a place full of pirates, fairies, and adventure. 'A Wrinkle in Time' also involves travel, as the characters tesser through space and time to different planets in search of their father. And 'The Chronicles of Narnia' series has multiple instances of the children traveling to the magical world of Narnia through a wardrobe.
Well, traveling to fictional universes is pure imagination for now. But in some sci-fi stories, it might involve advanced technology like wormholes or interdimensional portals.
Often, they end with the time traveler either returning to their original time or making peace with the new time they are in. For example, in 'Back to the Future', Marty McFly manages to return to his own time and also improves the future for his family. Sometimes, like in 'The Time Machine', the traveler continues on in the future they've reached, having learned something about humanity or themselves.
