We ran through one explanation after another, each one more alarming than the last. We wondered if it was a parasite, mold, or something that had come from inside the walls. The more we guessed, the more uneasy the bathroom began to feel, as if something had gone wrong without us knowing it.
Even though our fear started to feel unreasonable, it did not disappear. We kept debating whether it was dangerous, while the uncertainty made our imaginations worse. My girlfriend worried about leaks or toxins, and I tried to stay calm even as I felt uneasy myself.
When we finally found out it was only a harmless slime mold, the relief was huge. We cleaned the area, opened the windows, and later laughed at how strongly we had reacted. But the moment stayed with me, because once something ordinary suddenly feels strange, you never look at the same space in quite the same way again.
