Very subtle connection, but when Rachel is driving back to Ludlow she passes a sign for Jerusalem's Lot. Of course 'Salem's Lot introduces us to Father Callahan who we also meet in Calla Bryn Sturgis!

Within Pet Sematary, several of the characters mention Oz the great and "Tewwible". If you remember in the Dark Tower series, Roland comes across the home of Oz on the way to the tower. In Oz's home is the Man in black... No Oz the Great, but Oz the tewwible is in the castle of Oz....Perhaps the Pet Sematary and the surrounding burial ground is some type of portal between worlds that the Man in Black (oz the tewwible) is using to cause havok.. Further evidence: When people are brought back, they know things they could not possibly know. Perhaps they are under the control of the man in black. That would explain how they have telepathic abilities.

In chapter 19 Louis comments on Church's loss of his gunslinger ways after being neutered. "No more did he walk like a gunslinger" And of course Church is killed shortly after.
