When Hall Baltimore first goes to the hotel in the dream he orders just a beer. The beer is set in front of him and has a large head of foam. In the next scene the foam is gone. When the scene resumes the foam is back.
P.J.'s sitting position changes throughout the Ouija Board sequence.
In the newspaper clippings folder, the clipping from "The Press" (revealing the "Devil lives in the clock tower" angle) shows an ad for a motel on the left side of the page. In that page a car is shown, a 1957 Ford. In the next clipping shown, another variation on the "Devil in the clock tower" angle on the children's murders, shows the date of the newspaper, from 1955. Unless this paper was still churning the Devil in the tower angle, and the children's murder was still front page above the fold news (dubious), the car shown didn't exist until two years after the murder/newspaper story.
