When I was younger I saw something running on an alley right behind me, it wasn't a person, it wasn't an animal, a thing is the only way I can describe it. I was with a cousin and both of us ran most importantly, both of us saw and to this day we can't forget. It was all black and had bright red eyes the shape was like a person's but way bigger. What would've happened if we hadn't escaped? Where would we be if one of us stayed?
The thing disappeared the very moment we reached the end of the alley, completely.
