The TV show ‘Legion’ did exactly that brilliantly in my opinion. It dealt with a central protagonist who may or may not be experiencing psychosis, and just simply depicted reality and the perceived reality inside his head in precisely the same way. No differentiation between them. And no immediate explanation of any discontinuities and illogic. It was left up to the audience to make their own determination as to what was really going on from clues and connections that were dropped along the way. Very clever, and a demanding and therefore highly enjoyable experience.
