Distinguishing Fantasy from Reality

How does one know to distinguish fantasy from reality?

Here is a hypothetical scenario: let us say that there is a certain person afflicted with hallucinations, but their hallucinations are "non-bizarre". That is: the person isn't seeing anything overly unusual, like supernatural, paranormal, and/or conspiracy theory stuff. No demons, ghosts, aliens, deities, or anything like that. But this afflicted person is most definitely hallucinating.

What if this afflicted person has a somewhat unusual experience with no supernatural, paranormal, and/or conspiracy theory elements to it whatsoever. This unusual experience was a full-blown psychotic episode, complete with hallucinations affecting all of the senses: visual, auditory, tactile, olfactory, and gustatory hallucinations... the afflicted person assumes that this experience really happened in the physical world (in reality) among other real people who experienced the same exact things so that the general consensus is something that the afflicted person and everyone else involved can agree on.

So this afflicted person goes about their day assuming that this experience really happened. But then they start meeting with other people and talking to them, and those other people suddenly start saying things that contradict what the afflicted person experienced.

How can the afflicted person be certain that they did not simply hallucinate the entire experience?
