This happened a few months ago actually.
I was laying in my bed about to go to sleep, my family was going threw some bad times. I was turned towards my window but turned away and tried to calm my nerves and fall asleep. I then heard a distant laughter coming from outside. It was low and deep and was slightly echoing. Then I heard talking loudly in gibberish but it sounded like it was coming from a great distance away. It soon faded away and I turned to face my window and there was nothing there. I think it was demons.
