Bouquet

 I worked in a kindergarten, and on some holiday (March 8th, I think), all the employees were given flowers. When I got home, I put flowers in a vase with water.

At night, my mother called me from the next room and said in a sleepy voice:

— Daria, why are you wandering around in the dark, not letting me sleep? At least turn on the light, rather than trample around at random...

I was surprised.:

— Mom, I thought you were walking around the apartment for some reason...

In general, we were really scared. Someone was walking around the apartment as soon as we turned off the lights. So we slept with the lights on.

The next day at work, my mother told her colleagues about it, and one elderly woman asked if any new items had appeared in the house. When she found out that I had been given flowers, she said that they must have been plucked from the cemetery, so she brought the lost soul with her into the house...

And indeed, as soon as the flowers were thrown away, the night steps stopped scaring us.
