There's
Accidental Nightmare Fuel. Then there's
this. This is the stuff that is not only intentionally scary, but so horrifying that it can give people the creeps for
the rest of the day,
several days,
weeks,
months, or even
years. This is the stuff that can scare the pants off of just about anyone, possibly to the author/creator's delight. This is stuff that makes you shrink in the back of your chair, look over your shoulder, and remind yourself that what's going on is (usually) only fictional.
By way of comparison, when someone creates a work of fiction that wasn't supposed to be scary, but ends up giving its audience nightmares anyway, then it's
Accidental Nightmare Fuel. If it was only meant to scare kids, it's
Defanged Horrors. If it is meant to scare but fails to deliver, and
becomes hilarious instead, it devolves into
Nightmare Retardant.
For many
horror films, achieving this effect is the whole point (and many in-universe examples arise because
Kids Shouldn't Watch Horror Films). For
some reason, many of us like to be scared on purpose, there may be a euphoria generated by surviving something that seems scary, or maybe we know that fiction can't hurt us and the idea of choosing to be scared without the danger is fun. Some think it's cathartic or therapeutic in some way to explore our fears from a position of relative safety. In any case, this is normal for the genre. Others are
fascinated by the very things that most people avoid. Occasionally, it overlaps with
Squick.
High Octane Nightmare Fuel can also be accidental, when the creators of a work are trying to be frightening, and
wind up succeeding beyond their expectations or intentions.
Similarly, some
Public Service Announcements choose to employ terrifying imagery in order to
keep people away from doing dangerous things. These can be sources of
Fridge Horror as well, as those from different cultures or eras past can demonstrate some intensely creepy
Family-Unfriendly Aesops.
Experiences may vary from person to person. Some people, for example, may find the invasion of monstrosities which are treated as benign to be a far more terrifying prospect than things which we need to explicitly fear. Think the difference between the monster who lives under your bed when you're grown up versus the monster who lives under your bed and
fist-bumps your parents when you were a young child.
This trope couldn't be much more
subjective, so don't get too worked up about what specifically goes into it - what's
Nightmare Retardant for one person may well be
High Octane Nightmare Fuel for another.
Some examples of things that are generally High Octane Nightmare Fuel include - but are not limited to - the following:
- Surreal sequences, usually animated.
- Extreme violence and deaths.
- The disgusting images associated with Nausea Fuel.
- Unsettling body structures, human or not.
- Nightmare Dreams, disturbing dream sequences and hallucinations straight out of a nightmare.
- Horrifically mutated, distorted, injured, or... unreal faces.
- Spawn of Uncanny Valley (if it's used intentionally), anything that has crawled out of the valley.
- Clowns, if they're meant to be.
- Paranoia Fuel — when things that should be harmless, or on your side, turn nasty.
- Especially effective with fear of poisoning.
- Primal Fears: possibly the most universally frightening of the mix; stuff that generally everyone gets the creeps from. Includes but is not limited to:
- ...
- Adult Fears. Those things children seldom worry about: economic failure, romantic failure, watching helplessly as your children die, or possibly even The End of the World as We Know It.
- Transformation Sequences with plenty of Body Horror, including Chest Bursters.
- Rotting corpses, possibly reanimated.
- Diseases. They have no intelligence to bear anyone ill will, but once an infection/outbreak occurs, the attack will never stop until they are completely annihilated... or their victims are.
- Mutilation of specific body parts, such as the eyes, fingers, genitalia, or even worse than those injuries.
- Fates so horrific one can only wish for death. Being turned into stone, being trapped in another dimension, being encased in a tomb for eternity, being forcefully made into a machine without consent, or worse...
- A sexual or romantic obsession with someone that goes too far.
- The incredible depravity and monstrosity of human beings at their absolute worst.
- Psychotic behavior presented in a disturbingly childish, calm, or serene manner, alluding to the potential inhumane nature of the individual.
- Former heroes committing completely reprehensible acts both willingly or worse unwillingly.
- Surreal monsters and Eldritch Abominations that have horrific appearances.
- Soundtrack Dissonance, when used correctly, can make a scene extremely horrifying.
- Being pregnant with an Eldritch Abomination or other evil entity, or your child becoming one of these things.
- Losing all reason or willpower to continue living.
- A totalitarian authority of any kind so harsh that one wishes to die or escape from it.
- Death and destruction.
- Being inside a living creature.
- Consumption of people as food. Wanna take that many steps even further?
- Having your mind toyed with, be it wiping your memory out, Mind Control, brainwashing, re-enacting past horrific events, invasion of your thoughts, or whatever else one can think of.
- Being hunted and chased endlessly.
- Think you're safe behind the Fourth Wall because it is Fiction? THINK AGAIN!
Keep in mind:
This is a Subjective Trope. Some of the entries here may come off as nothing scary to you, and that's fine.
That does not give you the right to delete an entry or argue over it on its respective page. Calling someone a wimp because something that you don't mind creeped them out is rude.
