Books that fit or could have a similar prompt as those:

Scenes have explicit description of background music or their environment. Theater-Script inspired, maybe.

Alternative consciousnesses, whose experience is different than humans experience of reality

There are new colors, senses or non-existing dimensions of perception. (Just seeing magic would not go far enough here)

Relationships caused by the form of existence, without parallel in reality. Something like immortal <=> mortal, or 3 consciousnesses in one body managing it together.

Perspective of an inanimate object, like a sword that is passed around as its users get killed.

Mental magic to a degree where it's possible to change a characters personality (I guess quality of execution matters for this)

Demonic or Monsterous Ethics. Something that doesn't go for "demons can have a human experience their own way". I want to feel as alienated as possible.

Reading the story is part of the story. Kinda like in "The Neverending Story"

Not Reading is part of the story. Something like being told to rip out pages, Return to previous chapters, have a part in another medium like online content, or simply being forced to only read further when conditions are met (like "Only read on Friday" or "Continue when you are drunk" or "Read further naked")
