This 2018 short film was presented by Crypt TV in 2020.

A young girl is confronted by a monster when she's lying in bed at night, but it quickly becomes apparent that it can't get to her as long as she's completely covered by her bed sheet. That's really all there is to say about the plot, but it's a very effective short, and it's just really neat how it utilizes a concept that I dare say everyone is familiar with.
