Thank you very much to salvagebar, Gaffsey, weryllium, AidenEldritch, shaggydredlocks, and Lex1nat0r for their help.
Based on a weird incident that happened to me when I was home alone: my dog, who never barks, began barking at something in the forest near my home - as did every other dog in the neighbourhood. Amidst the barks, I heard something like a laugh… Later learned it was probably a coyote, but the image of every animals going crazy at the presence of something just stuck with me.
