This morning I noticed a pinkish mass on my wall and immediately called the landlord: I was horrified when I realized what it was 

I woke up this morning as usual, went to the kitchen to make coffee — and suddenly froze. On the wall, right where the kitchen meets the living room, I saw something strange: a pinkish substance was oozing out of a crack. It looked terrifying and disgusting.

Since I live in a rented apartment, I called the landlord right away. He arrived quickly — within half an hour he was there.

He glanced at it briefly, seemed irritated, and calmly said:

— It’s just some old insulating foam, nothing to worry about.

He took a tissue, put on gloves, wiped part of the mass from the wall, and left as if nothing had happened. But I felt he was hiding something.

His behavior made me uneasy. He seemed in a rush to leave and avoided any details. I decided I couldn’t just let it go.

After he left, I put on gloves, grabbed a flashlight and a knife, and carefully tried to peek inside the crack. Something inside… was moving. I panicked. The smell coming out was faint but unpleasant. When I finally realized what it was, I froze in terror

I took a photo and sent it to a biologist I know.

A few hours later, he called me back and said it looked like a fungal colony with mycelium, or possibly parasitic insects using the insulation material and wall warmth as a habitat.

This kind of thing happens in tropical areas or poorly ventilated spaces. According to him, it could have been growing for years — and if left untreated, it could pose a serious health risk, especially to the respiratory system.

I immediately left the apartment. The landlord hasn’t answered my calls since.

I can’t stop thinking — what if it wasn’t just mold? Why was he so quick to wipe it away? Why did he refuse to check further?

I’m scared there’s something inside that wall… something I maybe should have never found.
