This is a bug of the game. When you exit a world, or far enough from an area, everything except a few things would freeze, and do no change until the the next time you enter. It's mostly because otherwise the game would be hard to program, or very laggy.

If you got low sanity in the cave, and go back to overworld with shadow creatures chasing you, and restore sanity, and go there again, they will stay where they were. And they won't disappear, until you fight them for a while or lose sanity and restore again, which would be hard.
