Looking for fantastic literature involving dreams

Hello! I need to read an English-language work of fantastic literature and write a report about it. However, I am not very familiar with British or American fantastic literature. Could you recommend works of fantastic literature in which dreams play an important role, similar to Alice’s Adventures in Wonderland? I would truly appreciate any recommendations you can share.

If you have any time to spare, I would really appreciate it.🥺🥺🥺

*Fantastic literature is based on reality, and its stories usually begin in a world that is similar to our own. However, unreal or supernatural elements suddenly appear in this realistic setting. When this happens, readers begin to feel uncertain about whether the events are real or imaginary. In many cases, the story does not fully explain these strange events, which makes the situation more confusing. Because of this uncertainty and lack of explanation, fantastic literature often creates a sense of unease or anxiety. In short, fantastic literature deals with moments when reality starts to break down.
