Recently, I was watching (for the millionth time) Stanley Kubrik's The Shining.
One of my favourite scene is the first meeting between Jack Torrance and Lloyd.
At the beginning of that scene, we see a angry Jack that walks the hallway making some gestures of annoyance (or pure rage, Wendy had just accused him of having tried to strangle Danny).
On the left of the screen, we can see some mirrors in which Jack is reflected while he walks, but when he is near the Gold Room (the bar where he gets in and meet Lloyd), the mirror doesn't reflect Jack anymore.
Is this a clue that Jack is about to enter a "world of fantasy" created by the Overlook Hotel? Or is this simply a matter of perspective due to the camera movement?
Here the link of that scene, the mirror that I'm talking about appears near the 25th second of that video
