In the 1997 movie "Contact" the protagonist Ellie Arroway has an "experience" that nobody else shares in... and whereas her experience was 100% real and authentic, she is faced with the uphill challenge of persuading the world that her perception is actually real in spite of nobody else actually having had that same experience. Of course, that's a fictional case.

Because I'm feeling particular pedantic today (the result of being deep in philosophical matters), I call this example out.
It's only due to the nature of the film itself (the audience is observing her subjective experience, thus, then making it an objective one - which is impossible in reality .
Unless is verifiable , subjective truths can only ever be opinion or personal perspective. (ergo, making the premise of the film, moot).

Pedantic rant over! lol
