Trope about possibillity of stuff from media to reality.

Hi, I've been wondering, is there a trope that covers things that are supposedly possible in fiction but when done in real life it's not the same? Let me give you an example: There's the Film X where there's a song that drives people bat shit insane, we get to hear the song in certain parts of the movie and it, obviously, does what it says and the people on the screen just go mad, but when the audience listen to the song on the movie, the OST or play it in real life it obviously doesn't work.

Is this covered in a trope?

You want Trope Finder for this sort of inquiry, but I don't think that what you're suggesting is a trope.
