* AcidAttack: The Ramon C Herrera malformed miner tends to randomly spit corrosive acid that also gives off nerve gas fumes.

** When reviewing the Malformations, the warped construction team, it's noted Scott Oakhurst would act benevolent and friendly only to suddenly attack and partially eat victims and laugh while doing so.

** In ''back to normal'' a freeze frame shows a newspaper article mentioning Jim Melgren and mentions a few things that become clear in later videos. "There are horrifying reports of people-grown healthy adults-becoming deformed, growing extra limbs, teeth growing out of their scalp, people developing severe mental conditions, or even sickness." Tape 008 would reveal that not only were the Greylock miners getting ill but mutating and some even gaining powers from the disease/curse and likely were the ones breaking into homes.

* ItsProbablyNothing: In ''messages from the dead'', [[spoiler:Dr Albrecht explains that when his assistant told him she heard sobbing coming from the morgue's body storage, he sent her home, assuming she was exhausted. He then reveals that he, too, heard the sobbing - and ignores it until after returning home himself.]]

* {{Tulpa}}: the root cause of much of the issues in the series are tulpas - referred to as thoughtforms throughout - that the US government attempted to harness for military and industrial use.

-> ''The devil has a plan for you...''

--> ''We will at last reach the one called God. And there on His apex of infinite knowledge and power, we will approach Him and look Him in the eye as an equal.''

* WouldKillAChild: The thoughtforms don't seem to care much for how old their victims are; there are at least two cases of them murdering children.

* PoliticallyIncorrectVillain: In ''trojan technology'', [=SimioDyn=] president Percival C. Rothwell can be heard demeaning UsefulNotes/JohnFKennedy as a "fucking mick" for impeding the NAI program (implied to be the proximate reason the thoughtforms have become a threat).

* ''Tape 004 - unexpected visitors'', about a string of violent home invasions in Berkshire County, Massachusets

* EldritchLocation: The tunnels underneath Mt Greylock. They seemingly clear themselves of debris on their own shortly after being discovered, and they are filled with artifacts from dozens of ancient civillizations, including ones that have no business being in Massachusets, such as Ancient Greeks and Egyptians. The place also seems to compel the people who come across it to head in deeper, and acts as a BrownNote to all intruders.
