* HumanoidAbomination: Several cases are shown, but most notably several of TheMenInBlack and the Black-eyed Children they're rumored to be associated with. This is mainly due to their apparent ability to cause discomfort, both physical and mental, on people, as well as their general UncannyValley in trying to mimic actual human behavior.

** "The Battle of Ape Canyon" details miners in a battle for survival against gorilla-like monsters that they called Mountain Devils, which the Native Americans once knew as the Seeahtik tribe.

* EvilOldFolks: "Nightshift" features a guard encounter an angry ghost of an old woman in white.

* AdultFear: One of the many recurring themes in several of their episodes.
** A child or loved one disappears off the face of the Earth without a trace, especially when you were together with them just minutes ago.
** Finding out your loved ones, friends, etc. have died, but under very mysterious circumstances. Bonus points if you don't even find their bodies, [[NotEnoughToBury but just portions of clothing or just a handful of bones]].
** Your son delving into the occult thinking it's just a game, and suffering terrible consequences as a result, including unwittingly running away from home.
** As of Season 4, there's living as part of a BigScrewedUpFamily, including having to deal with AbusiveParents.
** The children under your care encountering something that terrified them and left many of them in tears.

* {{Ghostapo}}: Mentioned in "Secrets of Celle Neues Rathaus; a Nazi Occult Tale?", where one theory goes that the SS, under Himmler's orders, used the titular building for experiments into the occult, and that they had flooded the basement floors to [[SealedEvilInACan hide whatever monstrosities were created down there.]] And all of this quite possibly involved [[ObligatoryWarCrimeScene torturing Jewish prisoners]] from the nearby concentration camps.

* ObligatoryWarCrimeScene: One portion of "Secrets of Celle Neues Rathaus" depicts Jewish prisoners being tortured by the SS, for use as test subjects in occult research.

* RealLife/CoolPlane: Quite a few impressive warplanes from World War II and Vietnam are featured.
** The Grumman/General Motors TBM Avenger, the United States Navy's best torpedo bomber of UsefulNotes/WorldWarII, responsible for, among other achievements, sinking both ''Yamato''-class battleships of [[UsefulNotes/KatanasOfTheRisingSun the Imperial Japanese Navy]]. Unfortunately, the episode in which its featured in, "The Disappearance of Flight 19", is one of its most infamous incidents.
** The F-4 Phantom II and the B-52 Stratofortress are featured heavily in "Enemy Unknown". Unfortunately for the latter, however, its appearance in this episode is as one of 17 bombers lost during UsefulNotes/TheVietnamWar.
** "The New York Nuke" has the Junkers Ju 390, a SuperPrototype conventional, propeller-driven aircraft capable of flying all the way from France to New York City and back.

* EvilDetectingDog: In "The Monster of Morbach", the guard dogs refused to go anywhere near where the titular werewolf was spotted, almost as if they could sense how evil and dangerous they were.

* UncertainDoom: The fate of many missing people, from Carl Robert Disch and Kenny Veatch (who likely committed suicide and their bodies are somewhere difficult to locate) to the man known as David Christie (left ambiguous if his fate was connected to the "Kentucky Goblins").

* NoEnding: Oddly, "Highways of Horror - Novis et Tenebris" doesn't end with a segment with the narrator closing the video, with an explanation in the preview explaining there was little point as it would be repeating similar explanations to the past "Highways of Horror" video. It simply ends with finishing the last story. It doesn't even go into theories on what the mystery creature in Australia was.

** The face seen in "There is Something in the Valley", which appears to be almost scarecrow-like. It appears to be someone or something wearing the fac of another man.

* OurVampiresAreDifferent: "America's Vampires" has vampires that can pass off as normal humans during the day, suck the blood of victims at night, and have superhuman strength. No transforming into bats or other animals or known weakness to garlic, though.

* DeathOfAChild: As shown in several episodes, children are shown to be just as vulnerable a target as teenagers and adults to the paranormal and unexplained. An example in "What Killed Olivia Mabel?", the death of the titular character's 10-year old son is the motivation that apparently drives her into eventual suicide.

* HauntedTechnology: The infamous ''Little Bastard'' belonging to Creator/JamesDean, which includes ''all'' of its parts.
