In the later "Dark Tower" books, Stephen King writes himself into the narrative. In the sixth book, it's discovered that King is meant to get hit by a van and die on the date June 19, 1999. In the seventh book, he is rescued on that date from death by his own characters. In "11/22/63," this date is the day the Vermont Yankee nuclear reactor explodes. Derry, Maine is also mentioned in both this book and the series.

Jake Epping also sees a Takuro Spirit, a type of car found in alternate versions of America in the "Dark Tower" series.
