Renting a house, but hanging a small mirror on the kitchen window, I feel very uncomfortable. Who knows what this means?

Mirrors can ward off evil spirits. Hanging a mirror on the window can keep out evil spirits, that is, it can keep out bad things outside, such as ghosts and bad luck. Because in Feng Shui, the mirror can reflect these bad things, so that they can't enter the house.

This is a rented house. I think there are several possibilities. First, the previous owner was superstitious, so he hung this mirror. First, bad things have happened in this house before, and this mirror is hung to ward off evil spirits; It is also possible that a mirror is hung on the opposite floor, and the owner is afraid that those bad things on the opposite side will be reflected to his home, so he also hangs a mirror.
