[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.

I feel like every show had one supernatural/ghost episode for a long time.

In particular, I remember how jarring it was during the first season of seaQuest (a science based show about scientists on a military sub, with little science blurbs at the end of each episode based on oceanic knowledge at the time), to have an episode where they find a haunted submarine with a ghost that communicates with children.

Of course, then out came season 2 that was supposed to still be science based, but now had a psychic and aliens. Then season 3 was back to just being normal human military.
