The bubbles don't always appear. Swamps don't naturally drain sanity - it's the monsters that do that, and if you can't see monsters nearby, what's draining your sanity that you can't see? Tentacles!

Keeping an eye on the sanity meter is the best way to notice them, you don't need to hover the mouse over it and "wait", just watch the arrows. When it's daytime, any arrow pointing downwards with no monsters nearby = tentacle nearby. During dusk and night, a bigger arrow = tentacle nearby.
