Halloween is nigh, and once more scary stories are seeping through the dark crevices of the Internet.

One of latest is a short film that originated with a question asked last year at Reddit: "What is the best horror story you can come up with in two sentences?"

And if you didn't think it's possible to be absolutely terrified by just a few words, you'll think again. A resulting story by Reddit user Juan J. Ruiz (username justAnotherMuffledVo) went like this:

I begin tucking him into bed and he tells me, “Daddy check for monsters under my bed.” I look underneath for his amusement and see him, another him, under the bed, staring back at me quivering and whispering, “Daddy there’s somebody on my bed.”

Ruiz's horror story was then turned into the truly chilling one-minute clip above called "Tuck Me In," directed by Barcelona-based filmmaker Ignacio F. Rodó .
