This might be a bit of an odd question to ask about a game involving Cthulhu Mythos content, but do any keepers involve content of a mundane nature, and if so, how much?
When going from one gaming adventure to the next, I imagine that it's common that one simply says that a certain amount of time has gone by, assuming that the players have lived through the last adventure with their wits intact. This can allow your players to take a college course, read that moldering tome they found, seek therapy, etc.
There is however the potential for single sessions and even whole scenarios set within regular reality. I know of at least one published scenario that seems supernatural at first but turns out to be relatively normal. Various character types, namely Police and Criminals, could have pretty interesting stories without bringing monsters and gods into the mix.
A keeper could also make things more open-ended, allowing players to look into leads that don't end up having anything to do with the Cthulhu Mythos, which makes sense given how obscure and little-known such material is supposed to be in-game.
It likely depends on how regular your games are, of course. While the monsters are what bring people to the table, I don't necessarily want to make it look like tentacles are spilling out of every hole in the ground. And perhaps, sometimes, the murder you're investigating turns out to be a regular crime disguised to be a cult sacrifice. And of course, it also allows the players to use their characters without as much of a high likelihood of them being physically or mentally destroyed (not that they know this while playing).
I'm curious what others do in this regard, particularly any keepers who run a regular weekly/monthly game.
