My list of visions in "The Shining" are at the bottom of this page.
A vision is similar to a hallucination or an illusion, and a ghost is an actual presence that becomes manifest to the living. It’s very interesting that Stanley Kubrick doesn’t use either word, ghost or vision, when he has Dick Hallorann explain “Shining”, and what he might be seeing inside the hotel, to Danny. “Well, you know Doc, when something happens it can leave a trace of itself behind. Say like if someone burns toast. Well, maybe things that happened leave other kind of traces behind. Not things that anyone can notice, but things that people who 'shine' can see.”
He’s talking about Danny’s ability to “see” past events that have happened inside The Overlook, and he doesn’t say a word about ghosts or that The Overlook is haunted. He’s describing visions to Danny here not ghosts, and he would have indicated so if he was. In Stephen King’s novel he doesn’t know about “ghosts” either. The spirits are aroused because Danny is in the hotel and they want his power. In Stanley Kubrick's Overlook it’s Jack that arouses the "ghosts" after he opens the scrapbook we see sitting on his desk throughout the film. Jack is the only cast member that knows what The Overlook's previous guests all look like; Dick Hallorann doesn't!
In the movie Dick Hallorann doesn’t mention The Overlook being haunted, or that there are ghosts there, because he’s never perceived any of this himself and if he did know of these things he would have told Danny so (exactly like he explained his ability to “Shine”). What the Torrances’ are perceiving in The Overlook only happens after Jack arrives. To a screen audience a vision or a ghost would both appear the same. But if you look closely at the script Stanley Kubrick puts proof that characters can project these visions into each others minds. It appears that both Danny and Dick Hallorann experience the exact same vision of Jack entering room 237. Danny is in his room and Dick Hallorann is several thousand miles away yet they see the exact same thing. If it happens once it can happen many other times like when Jack kills Dick Hallorann, Danny sees it and screams while hiding inside the cabinet on the other side of the hotel.
The visions that characters in the movie experience are interesting and important to look at and I’ve listed each of them. Jack is at the Overlook during every vision that Danny Dick or Wendy have, and we know from the dialogue the exact spot where he has the opportunity to peer into the Overlook’s scrapbook (5:26 into the movie, “I’d like you to take him around the place soon as we’re through ... ”). Visions begin appearing to the characters right after that. Stanley Kubrick tells us in the dialogue that these visions aren't real, “Remember what Mr. Hallorann said. It's just like pictures in a book, Danny. It isn't real.”, and Dick Hallorann knows exactly what he’s talking about. In the movie the Torrance's see 21 separate visions. After Jack has the opportunity to open the scrapbook he knows exactly what all of The Overlook’s most notorious guests look like. The ones that didn’t make it onto the hotel’s walls, the ones that aren’t, “all the best people” that Mr. Ullman speaks about during their tour. The exact same guests that appear in their visions. If The Overlook was haunted Mr. Ullman would have been proud of it and told Jack that fact during the interview, after all he did tell him about the murders.
Stanley Kubrick got an idea for using certain colors from Stephen King’s novel where Dick Hallorann smelled oranges when he “Shined”. Being that smell can not yet be adequately brought across to a theater audience Stanley Kubrick made the brilliant decision to use the two pigments a painter mixes together to make the color orange, then use those as a visual device to indicate “Shining”. Here’s my list of the visions and I've indicated where the color red, yellow, or the color produced if you mix them together (orange) is present in each. Danny sees 9 visions (the audience only sees 8 of them) and they are in dark red. Jack sees 8 visions and they are in dark violet. Wendy sees 4 visions and they are in dark green. With the final vision seen only by the audience. Danny sees the bloody elevators, the women in room 237, and “Redrum” all twice, and he sees the Grady twins four times. Lloyd and Grady both talk to Jack twice. And Wendy’s visions appear to her only once each.
Jack arrives at the hotel and is taken on his first tour by Bill Watson where he has an opportunity to look into the scrapbook.
