A person sleeping in a futon can be found in one of the rooms of the Bright Moon Cottage. When looking at it directly, a loud breathing sound can be heard.
Sometimes the breathing sound can be heard downstairs in the bar area underneath it, potentially startling some unaware players.
The Dying Woman can be found in the same spot.
This object could represent the protagonist as they lucid dream. The protagonist may be noticing their breathing in real-live causing this to be loud.
