* The book "Incongruity" by best-selling horror author Michael Waite in the WhateleyUniverse. You're fine reading it, unless you happen to know that it is really The First Scroll of The Kellith, who is prophesied to wipe mankind off the face of the earth and re-populate the planet with the seed of the [[EldritchAbomination Great Old Ones]]. It also helps not to know that Michael Waite will ''become'' The Kellith.

** Also on B5, apparently nearly every sentient race has developed a dish almost identical to Swedish meatballs, when G'kar comments on this, his response is.
--> "It is one of the great mysteries of the universe, that we will either never know the answer to, or which would drive you quite mad if you did."
** Another one from G'kar: "There are things in the universe billions of years older than either of our races. They're vast, timeless, and if they're aware of us at all, it is as little more than ants, and we have as much chance of communicating with them as an ant has with us. We know, we've tried, and we've learned that we can either stay out from underfoot or be stepped on. [...] they are a mystery. And I am both terrified and reassured to know that there are still wonders in the universe, that we have not yet explained everything."

* In ''Series/DoctorWho'', Donna gets caught in the Meta-Crisis which creates a ''[[CloningBlues second]]'' Doctor, who as as a result becomes part-Human, while she gained a Time Lord mind. Unfortunately, it's a BrownNote, as over 900 years of Time Lord knowledge and experience shoved into her human brain almost kills her. To save her life, the Doctor has to permanently lock away ''all'' memory of him from her conscious mind.

* ''{{Series/Beyond}}'': Arthur believes journeying into the Realm (in the belief it's the afterlife, which living people can visit) is a very bad idea. He appears to be right, as it's not only unclear if the Realm really is the afterlife, but there are dangerous things there which do not want people of our world visiting.

** [[Recap/DoctorWhoS36E6Extremis "Extremis"]]: The Vatican has in its possession a TomeOfEldritchLore called ''The Veritas'', Latin for "truth". The truth revealed in the book is so horrible everyone who reads it is DrivenToSuicide. What ''is'' that truth? [[spoiler:The world is a computer simulation created by hostile aliens in preparation for their invasion of Earth.]]



* ''Series/MysteryScienceTheater3000'': After seeing Ed Wood's ''[[SoBadItsGood Bride of the Monster]]'', the line "He tampered in God's domain," became almost a CatchPhrase for Crow T. Robot.
* In ''Series/StargateSG1'' the Ancients' Repository of Knowledge devices (Jack referred to them as Ancient head suckers because of the way they latch onto the user's head) can download the entire knowledge bank of the Ancients into the mind of the user, however said information is too vast for the human mind to comprehend at our current evolutionary level. Therefore anyone exposed to the knowledge bank will have their minds completely taken over by it causing them to degrade and eventually shut down (die). Jack had his head sucked twice, and while he was able to build many advanced technologies, he was eventually unable to speak or comprehend anything other than the Ancient language and he nearly died from the strain on his brain- the second time he had to go into stasis to escape death.

* [[EldritchLocation The Nightmare Realm]] of ''WesternAnimation/GravityFalls'' is one of these. [[spoiler: Fiddleford [=McGucket=]]] accidentally gets sucked into it for a brief time, and when he comes out, [[spoiler:he's]] so horrifically traumatized that [[spoiler:he]] deliberately and repeatedly wipes [[spoiler: his]] own memory to the point of permanent brain damage, rendering [[spoiler: him]] a babbling fool.



* Parodied in ''WesternAnimation/TheTick'': "Let us not forget the lesson that we can learn from this, Arthur, that man was not meant to tamper with the four basic food groups."
* In a ''WesternAnimation/{{Teenage Mutant Ninja Turtles|2003}}'' episode, this line is spoken almost word for word by a panicked MadScientist working for the Foot Clan in a video journal that the Turtles find, describing the Shredder's horrid genetic experiment that turned human victims into mutants. (More than likely, the scientist and all other members of the Foot are dead by now.)
* Also parodied in the ''WesternAnimation/SpongebobSquarepants'' episode, "Plankton's Army", in a different way:
--> '''Mr. Krabs:''' ''(tied up, while Plankton is about to read the secret Krabby Patty formula/recipe)'' I'm telling you! You won't be able to handle the truth! There are some things in this world that weren't meant for mortal eyes!
--> '''[[{{Cyclops}} Plankton]]:''' Eye.
--> '''Mr. Krabs:''' [[TalkLikeAPirate Aye]].
--> '''Plankton:''' I don't care! Drum roll, please! ...The secret recipe for one Krabby Patty is: a pinch of salt... three teaspoons of chopped onions... a cup of love... mixed together with [[SecretIngredient the most important ingredient of all]]: four heaping pounds of freshly ground... ''(turns page, sees picture of himself) '''[[ImAHumanitarian plank]][[IAteWhat ton]]!?'''''
--> '''Mr. Krabs:''' I warned ya.
--> (Plankton [[GoMadFromTheRevelation screams]] and runs back to the Chum Bucket)
** [[spoiler:Fortunately for everyone, [[StatusQuoIsGod the recipe]] [[CrazyPrepared was a decoy.]]]]
* ''WesternAnimation/TheSimpsons'': Apu displays in his store as part of a promotion a can without a label. Otto says a line almost exactly the same as the trope title when he comes across it.



* In ''WesternAnimation/RickAndMorty'', this is the main reason Rick is so mentally disturbed: humanity was clearly never meant to have access to The Multiverse, encounter the horrors therein, and most importantly, face the existential nightmares it causes. He (barely) copes by being an alcoholic hedonistic sociopath.

** It gets better. The Correspondence's nasty effects are caused by writing them improperly, IE bad grammar. When used correctly it is a [[spoiler: [[RealityWarper reality warping]] LANGUAGE]]. This is because [[spoiler: it is the language of the Judgements, AKA the stars. They decide what is and what is not in their domains. In the Neath there is no Judgement keeping things normal.]] Which is why so [[MirrorMonster many]] [[EldritchAbomination crazy]] [[HumanoidAbomination things]] exist down there, why [[GoMadFromTheRevelation so many people are crazy]] and why [[RealityIsOutToLunch death is on extended leave.]]

** The Hist are a race of [[TimeAbyss ancient]], [[WiseTree sentient]], and possibly {{Omniscient}} trees native to the Black Marsh where they are worshiped by the [[LizardFolk Argonians]].

* [[BigBad Zeref]] of ''Manga/FairyTail'' is the living proof of what happens when you delve too deeply into taboo magic. He wanted desperately to [[spoiler:bring his younger brother Natsu BackFromTheDead]], and in the process not only studied various forbidden magics, but also created several magical theories most sane mages would never touch. The price? He was [[{{Curse}} cursed]] to [[spoiler:kill anybody he could ever care about or even being in the same general area]] as him, with [[WhoWantsToLiveForever immortality]] to boot as well as live long enough to see many of his works be misused. However, this immortality also bought him time [[spoiler:to succeed in his original goal of bringing his brother back]], and he didn't become [[ThenLetMeBeEvil evil]] until much later.

** Give a witness too much truth serum, in a court, and he'll tell "the whole truth". ALL of it. Oddly enough, the guy who comes to know all the truth doesn't seem to become mad - those who hear from him, though, do. This may be because he knows ''all'' the truth, whereas the listeners only know the part they hear. Oddly enough again, most of the good bits are about frogs.
