The Scent of Incense

There was a large house, and an old man lived there alone. He passed away while taking a bath (Be careful of temperature changes when bathing in winter). The house was demolished and sold as individual lots, and someone is now living in one of them. The location is essentially the bathroom on the neighbor's property. I heard this when talking to the neighbor. 'When I take a bath, the scent of incense comes from somewhere...' Even though the bathroom should be filled with the scent of shampoo and other products, when I soak in the tub and take a breath, I smell incense. Of course, we haven't lit any incense, and there's no Buddhist altar in the first place. What's more, apparently only the husband can smell it. Other than that, there's nothing particularly unusual, and she doesn't dislike the smell of incense, so she's just living there. They even had a child and seem happy, so there doesn't seem to be anything to worry about, but it was a bit of a strange story.
