This morning, you probably woke up to your normal routine (maybe slightly augmented by falling back an hour in time). You hopped in the shower, brushed your teeth, drank some orange juice with breakfast, and cursed yourself for the thousandth time for drinking orange juice after brushing your teeth. Most of all though, you felt safe. And you had no idea there was a man sleeping under your bed. Director Jaume Balagueró (REC, REC 2) uses that uneasy non-knowledge for both horror and humor in Sleep Tight (Mientras Duermes), a film that balances precariously over the Dark Comedy and Funny Home Invasion genre bins. The overall result is chilling proof that Balagueró can take us back into an apartment building while delivering a completely different scare.
