REC (film)/Nightmare Fuel

• The last 20 minutes or so of the first film. Think of it this way: You're stumbling around in pitch blackness, dependent on the night vision on a guy's video camera in order to see any of the bad things you know you're locked in the building with... which are all demon-possessed rage zombies. Sweet dreams.
• Any time Jennifer is shown after she becomes infected, especially the way she just suddenly appears behind everyone else as they're looking for her.
• [REC]3: Clara becoming an infected and ripping out Koldo´s tongue and lips as they kiss. If that was not gore, then I don´t know what it was. It even becomes worse by the fact that they are immediately shot and killed by the soldiers who are surrounding then
• [REC]2: The infected children. Enough said
