I think Jack Torrence was reincarnated in the Shining. Remember when ol' Jeevsy bumps into him in the Gold room and spills his drink on him? Here's the convo:
Jack Torrance: Mr. Grady, You WERE the caretaker here.
Delbert Grady: I'm sorry to differ with you sir, but YOU are the caretaker. You've always been the caretaker. I should know sir.: I've always been here.
