This is what you call psychological horror. You twist something that is perfectly benign and commonplace in everyday life into something that can make you scream. Director Ignacio F. Rodo does not overplay the turn and intentionally refrains from any loud scares. It works. "Tuck Me In" is one of the most disturbing horror shorts I've seen in years. Best of all? Rodo accomplished this in under a minute. That's impressive.
