Conveyance requires a source and a destination. To have an experience conveyed to you means to gain a degree of understanding of another's experience which you yourself did not have. Yet you yourself have not actually experienced it, you have merely gained knowledge into some aspects of it's nature by comparing it to your own experiences.

If a reader perceives that they have been conveyed an experience that nobody has ever had, then they have made up an imaginary experience which does not correspond to anybody else's lived reality, which may or may not be possible to have. If an LLM conveys an actual human experience, it is only because somebody's actual experience has been anonymized and conveyed on to you.
