The movie "Sucker Punch" and the "Once Upon a time" series make it hard to distinguish what state of reality is the "real" one (not that it matters).
In "Fixing the Shadow" we encountered a character who was either a cop who has infiltrated a biker gang or a biker member who used to be a cop. It was indistinguishable. But that was only a single reality where the character only had to choose.
The characters actions have the same interpretation in different realities (Sucker Punch), but in "Once upon a time" a fictional reality completes the real reality.
Sorry for blabbering on, but I hope I have managed to convey what I am trying to ask for.
