[[WMG: In the novel, the picture window never breaks.]]
The window that has all the FauxShadowing towards being broken survives [[spoiler: the boiler explosion]]. It is shielded from shattering by a miraculous confluence of events and a heavily faulty frame, and the pane itself ends up slicing into a dense snow drift some ways away completely undamaged.

[[WMG: The Overlook Hotel is an entity like [[Film/FourteenOhEight 1408]]...]]
... only all grown up.

[[WMG: Ulman and Watson knew the Overlook was haunted.]]
The way they talked to Jack about it was like they were hiding something. Scandals are one thing, but they seemed frightened by what they are hiding.

[[WMG: Ulman not only knows about the hauntings, he has made a deal with the entity and all it's ghostly representations.]]
He feeds it souls and psychic energy and they don't bother his guests for the summer season, save for a few glimpses. Why else would the hotel be somewhat normal in the summer, but [[BringMyBrownPants piss your pants scary]] in the winter?
* That might also explain why the Overlook did not become profitable until after Ulman took over as the manager, despite already having been around for decades at that point.
* Or, the hauntings only made themselves known to certain people, especially those who has a family member that has the Shining.

[[WMG: The Overlook is the nesting site of a powerful [[TabletopGame/WerewolfTheApocalypse Bane spirit]].]]
The "burial ground" explanation was a mistranslation by the white settlers. Unfortunately when the hotel was built, the native protesters who were killed included the Uktena Bane Tender who was keeping the... ''thing'' sleeping under the earth.

[[WMG: The Overlook was built by the [[DoctorSleep True Knot]] ]]
They wanted to make a conduit that could harvest as much Shining Steam as possible. However, somewhere along the line the energy from the Shining somehow gave the Overlook a mind of its own. Not that it mattered to the True Knot. However [[spoiler: after the boiler blew]], they had to find other means of harvesting it.
* This would help explain the hotel's intense interest in Danny, who presumably had some very strong steam.

[[WMG: Redrum could have a literal supernatural meaning apart from just being "Murder" spelled backwards.]]
It could mean "Red Rum" (alcohol); as in the bloodshed of at least two winter caretakers who went insane under CabinFever and several hotel guests over the years somehow fuel and/or 'intoxicate' the massive paranormal force of the hotel.
* I think the symbolism is really much simpler then that. Red rum. Blood.
