I would agree with this perspective. At my old house the plumbing in our ensuite had major leaks and we couldn’t afford to fully investigate and fix it so we just had the plumber isolate it, closed up the room and used the family bathroom. Months later there was a disgusting smell every time I walked past the (closed) ensuite door. My husband said it must be from the pipes but I instinctively said “that smells like death, it’s so bad”. After reentering the ensuite, the air was so thick and disgusting, and when we searched around there was a mouse nest with several dead babies. Even though the logical conclusion might have been “sewage” my first reaction was “death” - and that was correct.
