"Nightmares" is an apt name for the episode.
- "Nightmares", of course. Examples include a roller coaster ride in the middle (and aftermath) of an nuclear holocaust, an army of creepy monsters with baby heads and knives for legs, a woman running towards the camera with the background distorted and blood coming out of her mouth, and a monster made entirely out of hands (with a Jump Scare, too!). Special mention to the guy covered in gore breathing at the screen for a full 30 seconds.
- "Clowns" predictably plays with the idea of "creepy clowns", featuring shorts like a creepy clown edging closer to a security camera, a drone dressed like a creepy clown flying around a neighborhood, etc.
- "Animals" opens up with a jumpscare of somebody's head exploding off their body. While it isn't graphic at all, it can still be pretty startling to first time viewers, especially with the horrible shrieking.
- The "prebirth" short in Sound has 3 pyramid-head shaped aliens standing in front of a podium. One proceeds to spit out a baby, and out of nowhere violently whacks it against the podium. Then they proceed to get more and use them like drumsticks.
- Somewhat predictably, "Body" has quite a lot of body horror in it.
- Special mention goes to the rubbery-looking CGI man twitching about like a ragdoll down the street.
- Certain parts of "Worship" are pretty creepy, especially the 'Hypnogogs' short.
- The Psycho city short from "Transportation." Has distorted screaming getting louder and louder in the background.
- Less than 15 seconds into the episode, "Death" cuts without warning to a rapid-fire series of images depicting roadkill set to heavy metal music. The featured music videos for "Arterial" and "Beat the Drum Slowly" are also pretty creepy.
- "Holes" features a video of two cowboys staring each other down before a duel. Staring each other down hard. So hard that it quickly becomes comical. Then their faces start to collapse in on themselves. It doesn't help that a third cowboy shows up and starts spewing blood when his face randomly implodes.
- The "Hell/????" segment from the Space episode is horrifying to say the least.
- "Bugs" has a short called "Earworm", where two guys pick up a tape with a note that says "DO NOT PLAY", and for good reason. Once played, a worm comes out of the tape and attacks them, with them thankfully throwing the tape out. It is then picked up a girl, who plays the in her earbuds, leading to her face melting graphically.
