As a theme, disconnection is a heavy one.
There’s the fact that the Torrance family is only seen as a family unit within 3 scenes: No.9 when they’re driving up to The Overlook, partially in No.15 as Danny is brought to everyone when trying to look for them, and in No.17.
The lights shown in the exterior shots of the hotel are shown in very distant separate parts, and one could argue that Jack becomes disconnected from reality at the end; unable to recognize that he has the tool to set himself free if he could access his human skills (using tools.. and the brain).
