I hope that I never see that face, ever, outside of a dream.
  • The infamous scene featuring two guys, a diner, and something resembling a zombie hobo out back.
    • Also a little meta-Harsher in Hindsight. Remember when the one guy says "I hope I never see that face outside of a dream"? Flash forward 5 years to Inland Empire and, well...we get to find out exactly how he was feeling.
  • Sierra Boniokayta. This is when the film takes a much darker turn, as Betty and Rita investigate the apartment of Diane Selwyn, looking for answers regarding Rita's true identity. Do they find anything? Yes: Diane's decaying corpse in a bed. The neighbor's knocking on the door somehow makes it worse.
  • Much of the film's cinematography style and soundtrack.
  • The old couple with the ghastly grins.
  • Llorando. What starts as an ominous stage performance gradually shifts into a Tear Jerker, and somehow becomes more terrifying the longer it goes on. The film goes straight into Mind Screw territory just after.
  • The lady on Silencio Club's balcony is definitely creepy. Though the only line she has is rather Nightmare Retardant.
