Another story from my childhood.
One evening I was at home alone, I heard dogs barking very strangely in the yard, I went out and saw one of the dogs dragging a chicken in its mouth, which for some reason wasn't in the chicken coop. I took the chicken away from the dog and brought it into the house in the hope of bringing it back to life, but the barking resumed again. Coming out a second time, I realized that something strange was happening in the chicken coop. Stepping closer I saw a strange creature, it looked at me, the light from the lantern reflected in it's eyes and the creature disappeared, leaving behind almost a dozen decapitated chickens.
Of course, in fact it was just a marten, but otherwise it was something like this.
