The miasmic fog hung low over the swamp, creating an eerie atmosphere.
The abandoned house was filled with a miasmic odor that made my stomach turn.
The miasmic atmosphere of the old library seemed to seep into my bones as I walked through it.
The miasmic swamp was a breeding ground for all sorts of creepy creatures.
The town was shrouded in a miasmic haze, making it difficult to see more than a few feet ahead.
