I thought about this weird pattern for a second, because she had never done that sort of thing before. Whenever I had been out there in the past, if she turned her light on it simply stayed on until I went inside. She has never done this on, off, on, off, on before. I started to make a few connections in my head and right away thought of that urban legend where a lady unknowingly gets into her car with a killer in the backseat, and the 'asshole' truck driver behind her keeps riding her bumper, while flashing his high beams to alert the woman to the danger.This made me nope the fuck out when I started to see the similarities. Was this supposedly nosey, middle aged woman flashing her porchlight at me to alert me to something that I didn't notice? I have about a 6ft tall fence around my yard. Something could've have been waiting in the darkness on the other side of the fence, where only she could see due to being atop a hill. This also got me creeped at the cat meowing. One of those things could be aware that I have a cat, and tried to mimic the meow to try to lure me over. As soon as I connected these dots I shat some brix and went right back inside. She never flickered her light again. I didn't fall asleep until about 6 when the sun came up.And that's my story
