A Quiet Side points out the set and hotel layout was intentionally impossible in some places. The hotel was a combination of 3 different real hotels. He suggests that was to make the hotel seem like a maze you couldn’t escape.

Even more interesting is he’s created probably the most architecturally accurate fully navigable 3D model of the Overlook Hotel in Enscape (download here). In doing so, he really shows off the impossible architectures the hotel has.

More than just confusion or giving the sense of a maze, I almost took it as a dream. I have occasionally had dreams in which you walk through a door from one place to a completely other place, or impossible switches from one place to another.

Kubrick does a good job of keeping this subtle enough that most people don’t notice these details even on re-watching.
But what if it were just a little bit more overt. What if you made a movie about being trapped in a hotel/place in which the past and future blend much more seamlessly forward and backwards in time, as well geometry that was arranged by locations where some horror or another happened more than just a logical layout. Where it’s much more dream-like and areas are connected by associations instead of physical layout? You would have to keep it very subtle to avoid it becoming the movie Inception or overdoing it; but it is and interesting idea to explore…
