My wife came across it on Tumblr, though I think it was big on reddit too. And your wording isn't so good but I love the idea. Let me give it a try.
"I often talked aloud to my dark room after going to bed because it was fun thinking that something in that darkness could hear me, and so one night I asked the darkness how it was doing. A dry rasping voice answered me, saying it was hungry, so very hungry, and I haven't turned off the light in my room since."
