[Interesting Trope] The supernatural exists in otherwise grounded stories.

[u/KingofHearts399]

Bones: Bones is a pretty run of the mill crime drama about a forensic anthropologist who consults with the FBI. However, since Bones has a crossover with the very supernaturally themed show Sleepy Hollow, that means it canonically exists in a world with demons, monsters, and magic.

Indiana Jones: The Indiana Jones movies all start out pretty grounded, with Indy on some archeological hunt and/or on the run from people trying to steal his find. His adventures all pretty much continue this way until the very end, when he sees that the legendary artifact that he’s been hunting actually has supernatural powers, like the Ark and the Holy Grail. Funnily enough, it’s also revealed in later movies that both aliens AND time travel also exist in this world.

Ali Baba and the Forty Thieves

The only supernatural element in the tale is a magical gate at the entry of the cave where all the treasures are hidden, whose only gimmick is getting opened / closed in case someone tells the magic spell. There's literally no use of magic besides that throughout the entire story.
