In order for Nightmare Fuel tabs to survive, a new writing style is going to be used, nicknamed Example Lobotomy. Basic rules: Just list facts as they are. Don't just say "character X" or "the X scene" (such zero context examples will be zapped). Spoiler policy to be determined on a case-by-case basis. Italics to be applied to works' names only and not to give emphasis on what tropers say. "X scared me" is already implied by the mere addition of that example by the troper.
Try exploring a deep cave with the ambiance sounds and mob noises, without getting paranoid.
Have you ever came across a giant spider? Well in Minecraft the huge beasts are everywhere and they have a near insatiable appetite for human flesh. Have you ever found a Skeleton riding a spider? What's worse is, spiders have a 1% chance of spawning as one. They can also do that in Spider spawning dungeons.
And spiders can climb walls.
If you have a 2 high, 1 wide door and a 3 high ceiling, spiders will now cluster on the ceiling trying to get to you.
As of 1.8, there are now poisonous Cave Spiders. They are smaller than but easily more dangerous than the larger spiders. They are highly venomous and since they once come from spawners almost always attack in large groups. They are only found in abandoned mine shafts which are filled with webs which are easy to get stuck in; spiders are not.
Early on, when you're still getting used to the the game, you build a skylight, and see a spider step onto it every time you walk by. Then you realize it's tracking your movements from your roof, and will be right above you when you leave your base in the morning.
The entire Nether dimension qualifies. It has Ghasts flying around trying to kill you, lava all over, and Zombie Pigmen all over. Its biome name is even called "Hell".
Not only that, look at the ghast's face. It's crying as it kills you.
When you wake up, you know that there are Creepers outside in the morning, but not where they may be.
Hearing a monster noise out of nowhere, but not knowing where (again).
The range at which you can hear a mob is 16 blocks. Now realize the range at which a mob can sense you is 16 block; this means that if you can hear it it can find you, and if it finds you you are probably 5 seconds away from being mobbed by zombies. This can make anyone paranoid of noises in Minecraft.
You've just used up most of your tools, and it's getting dark out. You've only a few torches left (perhaps none if you went full out) as you're running from the cave you just finished excavating, and the sky is getting very dark, so you're making a bee-line for the camp/lodging you made yourself... and all too late do you fall down that nearly bottomless pit that is a vertical drop into complete darkness.
Also in this update: Squids.◊ They're kinda cute. Until you see their mouth◊ (though mercifully, squids are completely harmless).
Ghasts. Imagine big, white, house-sized... Jellyfish-like things, with faces, which have rather pained expressions, and they spit fire at you whilst crying. They sound like a crying baby, can be heard from far away.
If you are foolish enough to go to bed where monsters can get you, you'll doze off and go to sleep... only to be immediately woken up by a monster right beside you.
This was removed in a later update. Now, the game won't let you go to sleep if there are monsters nearby.
Which also had the side-effect of letting you sleep in the open, as long as there aren't any hostile mobs close by.
Carefully exploring a new branch of this massive cave... around a corner... TWANG! Skeleton shoots you from behind.
So you're wandering around in the daytime, minding your own business, looking around for enemies, and getting resources. Then you hear the sound of a Creeper.
Somewhere, out there, a Creeper is plotting to kill you.
Imagine this: it's your first time playing Minecraft. You're running around a happy, bright field, looking for some trees to get some wood from, when you suddenly step over the edge of a deep gorge you had no idea existed until a few moments ago and fall in. Taking a look around, you find no discernible exit and a Creeper lurking in an alcove, staring directly at you and doing absolutely nothing - waiting for you to pass by so it can spring out and blow you up.
Creepers hit by lightning turn into power creepers◊, which are not only scarier, but are also more powerful.
The Minecraft Wiki's advice for dealing with one? "Run."
The (now gone) Far Lands. More or less, if you head an impossibly far distance away from your spawn, the world basically goes batshit insane, creating:
Bedrock to sky walls of randomly generated, swiss cheese looking, non-natural in any way formations;
Strange, three layered planes, one on top of another:
The top, devoid of life, and with most blocks that usually fall (sand, gravel) completely ignoring gravity;
The middle pitch black and filled with mobs which, due to the fact that you have more or less stepped into the twilight zone, will spawn at a rate so fast that it is literally impossible to kill them fast enough, and
A bottom layer consisting entirely of an ocean filled with squids.
And, if you go even farther out, you eventually hit a point where the game stops generating light. Going beyond this (with the help of mods to see) gives you the worst experience off all: nothing.
Sheer cliffs all around, with strange, unnatural looking landmarks, and no mobs, trees, or anything to keep you company. Nothing but sand, dirt, and stone.
The Minecraft Wiki has some lovely images that show the Far Lands twisting blocks out of shape once you get deep enough in them. For a character used to simple, even square shapes like the Player Character, the Mind Screw is probably quadrupled. Oh, and MC Edit gets distorted by attempting to edit the Far Lands, too - everything related to that region is just pure Nightmare Fuel.
Even worse, the Nether also has Far Lands. Take the normal Far Lands, and put it in hell.
(Fortunately) Dead. Now you get oceans...and oceans...and oceans... oh and you will fall into "fake chunks" and die. Enjoy!
Soul Sand. It sinks you in a bit (like video game quicksand) and slows you down. It has faces on it. Faces that look like Creeper faces. Put that together and think about why it's called Soul Sand for a moment.
You are alone in this massive world save for animals, zombies, skeletons, and whatever the hell Creepers are. What happened to everyone?
1.8 also added the Endermen◊, a terrifying cross between Slender Man and a Weeping Angel. This blog post explains exactly what they do. When you have one in your sights, it looks right at you, opens its mouth, and starts shaking and smoking it keeps shaking even when you pause the game.
Even worse, the other possible name for endermen was "farlanders." Notch has stated that yes, Endermen come from the aforementioned Far Lands.
Endermen are weak to water. Endermen can teleport. It rains in Minecraft. Your house is dry.
Imagine a world with no stars, no moon or sun, the sky a void made of static noise, no trees, entirely made of a barren, dry stone and weird, obsidian towers. No oceans, no villages, no forms of life besides a throng of Endermen mindlessly walking around until they spot you. Add a humongous dragon supposedly made of antimatter, and that's The End. And once you beat the dragon, if you come back there for any reason, everything will be gone. Oh, and it is speculated that Endermen are stealing blocks from your world to attempt and restore their dimension, which the Enderdragon has turned into the barren, moon-like floating islands.
It's a Point of No Return. The only way out is to kill the Enderdragon...or die. Let's just say that on Hardcore mode, you damn better be carrying enough weaponry and food. Plus, you can't quit until you beat the dragon, or else when you come back to the game, there'll be another one.
A recent update gave the Enderdragon it's own sounds; actual dragon like sounds mixed in with bass undertones. It's death sound is especially unnerving to say the least.
Some kindly contributors at deviantART have been kind enough to provide us with approximations of what each mob would look like in a realistic setting. We have zombies, creepers,skeletons and spiders, zombie pigmen,and the ever adorable ghasts. It's sad when the Slenderman Expy is currently the least scary in fan-art, but knowing the internet, worse is sure to follow.
Silverfish are small, fast critters that might spawn when you destroy a stone block in a Stronghold. They look like some kind of hybrid between a real silverfish and a centipede except a hundred times larger, are hard to kill and spawn more of their kind out of nearby blocks whenever they are hit.
Now, they can be found in random blocks throughout the world, stronghold or not. Imagine you're mining out to make an underground house, and you break a block with them in it. Enjoy the rush
Abandoned Mine shafts. They're deep underground, dark and lonely. Part of them become labyrinth-like and easy to get lost in, while hearing the sounds of skeletons, zombies and spiders, regular and cave spiders clashing against dead silence (except for the occasional ambience)
Something about their construction is really unsettling too. Cart rails frequently disappear over the edge of what appear to be vertical shafts, except unlike in an actual mine, they don't have a clearly defined top or bottom. Just wooden pillars looming up and dropping away into the darkness...
The latest 1.9 prerelease introduced a lot of new music discs. Most of these are pretty innocent. All except one, which is simply titled "11". For one thing, it seems to be cracked and broken. For another, it doesn't play music. It plays the sounds of somebody running for their lives, running from something. Then it suddenly cuts out.
The new Release Candidate gives the Endermen really weird and creepy sounds. You may want to turn your volume down before you kill one. The new teleport sound is also rather creepy as well.
If you jump from a large height in 1.0, you can literally hear your bones crack as you hit the ground.
Thankfully, by 1.4, it's now just a *thump* when you take fall damage.
Notch might have something really scary going on with the number 11. Disc 11 is scary as hell, Endermen are the 11th mob added, and Herobrine has been removed 11 times.
And 1.1 was the only update that didn't list Herobrine as "removed" since he was first "removed". 1.1 minus a "." equals.. 11.
Hardcore mode. Imagine not only getting unluckily owned by a creeper or some other horrid abomination...but also having all your hard work taken away from you. This basically means you will seriously have to survive to the best of your abilities, and take almost zero risks for some time. For once you die... Game Over...
Chunk errors. A glitch where your world renders incorrectly and you can see a giant hole going through the ground/water/etc. Can be a Good Bad Bug, because it can help you locate mineral deposits and lava flows and so on, but you can walk over it and see Zombies, Creepers, Sheep, NPC's, etc. endlessly falling to their doom. Even when it happens to a monster, it's still pretty creepy.
As of the new pre-releases for 1.2, wolves, creepers and zombies have been given path-finding abilities, meaning they can go around lava and other hazards and will stalk you.
Putting Endermen in a game? Creepy and a bit challenging, but fairly easy to avoid. Putting Endermen in the same game that already had Creepers? Asking for trouble. For the uninitiated, a savvy player's first reaction to entering a new, dark area is to quickly look around to make sure there's nothing dangerous nearby. But now you're running the risk of accidentally looking at an Enderman that way. Suddenly no strategy is safe anymore...
Also applies to exploring underground caves and tunnels. Even if you can't see them in the pitch darkness in front of you, they can see you looking at them and will respond just as aggressively as they normally do.
Underground ravines. There is no good level to enter one from. Enter near the top and you're stuck edging along the narrow ledges and praying you don't screw up and fall, and you might not even bother because all the best ore blocks are near the bottom. Enter near the bottom and every creeper that spawns on one of the aforementioned ledges within a reasonable radius will decide to take a flying leap and come join you. And often the fall isn't enough to kill them.
Void fog. Now imaging being in a ravine where you can't see anything above you and very little ahead of you. Now realize that enemies see you perfectly in the fog...
In version 1.2, the zombies gain the ability break doors. Ready for a surprise visit?
Only in hard mode though. Still leaves you unable to sleep unless you have a way to stop them getting to you.
Snapshot 12w06a introduced rare drops from some mobs. Zombies have a rare chance to drop Iron things. It's pretty cool, until you realize...that iron may have been the spoils of other miners the Zombies have killed.
Or worse, it could have something to do with how they died.
Even if you're playing on peaceful, the cave noises can still freak you out. And sometimes updates will reset your settings, and if you forget to put it back on peaceful you can get ambushed by monsters.
Sometimes, in the Nether, you can see a massive, truly massive ocean of lava. All the lavafalls pour into it, creating this great sea of fire. And that's when it sinks in that you are, in fact, standing in Hell.
The acrophobia is strong with this one... seriously. You will discover a fear of hieghts as you move along a narrow ledge over a hundred feet above the cold hard ground below. Even if you don't build really tall structures you're still not safe. All it takes is one misstep in the wrong place and suddenly you're falling to your doom off the side of a mountain, cliff, or hole you just now noticed. It doesn't help that many types of buildings require the player to get near the ledge of something to place blocks...
Holding the SHIFT key prevents you from falling, though. Just be sure your finger doesn't slip when you're teetering on the edge of a block...
In the 1.3 update, zombie pigmen spawn (albeit rarely) near Nether Gates in Overworld. Sweet dream ensues.
Herobrine may not be real, but DAMN is he scary. Glowing white eyes, alters the world as he pleases, and he never stops hunting you, ever. Basically, he's Minecraft's version of Slender Man. Oh, and his pre-curbstomp catchphrase? "Only God can save you now".
Apparently, the experiment is going to be repeated, by the same person who ran the first one.
The X-box maps aren't unlimited, does that mean if they stay on survival and get enough players it'll happen the same?
The Wither. An Eldritch Abomination with three heads. It can shoot skulls that inflict a form of poison that can actually kill you for once. It also can destroy ice and will also attack any passive mobs. It's not certain where it spawns, but my money's on the Nether. Just think... Walking the Nether, no trouble, then "oh god, what is that?!"
Even scarier is what the message is for succumbing to this effect; "(name here) has withered away". Oh yeah, and arrows at close range bounce off, and the status effect it inflicts somehow heals it.
Oh! And that isn't eating through blocks in the sense of acid or whatever: as far as anyone can tell, the Wither literally devours the world . With a crunching noise and everything. It's as terrifying as it is bizarre.
Luckly, the Wither Boss itself only spawns if you summon it.
His the Wither Skeletons. They are some horrific amalgamation of the Zombie, the Skeleton and the Enderman, inflict the Wither status effect, and can kill you within three hits on Medium. Unlike the Wither, they are regular mobs in the Nether, and they're aggressive. They also rarely drop Wither Skulls, used to summon the Wither Boss. Have fun.
The Water world. *
If you don't know what this is, if you go to "More World Options" when making a new world, and change it to superflat, you can mess around with the options until it's not a grass world but a giant ocean.
It's this giant... ocean that is incredibly deep and literally has no end... If you're aquaphobic *
fear of water
or achluphobic *
fear of darkness since it's pretty dang dark down there...
than don't go to this world!
Speaking of quirks of superflat, the flying Abandoned Mineshafts generated on certain custom superflat conditions can be large. Very large. Very, VERY◊ large*
What's more, that screenshot is with maximum render distance set but still can't display the entire thing. In fact, what you can see there is only a half of that particular mineshaft.
. Imagine if it were a closed-in cavern like in a normal game, complete with darkness, loss of direction, and hostile enemies, but still that size... You'd be lost in it forever.
The 1.4 "Pretty Scary Update" updated the sounds of mobs. By far the worst is the Endermen. If you anger one, they make a horrific mix of a growl and a scream, and it always sounds as if they're right next to you (Which, thanks to their teleporting ability, they probably will be.) Hearing it is bad enough. Hearing it out of no-where after looking into a pitch-dark cave is pants-wetting.
The noise they make when you stare at them as of 1.4 is pretty dang frightening too. It combines a sinister growl, static, and what sounds like a plane taking off in the most horrifying way possible. Hearing it on its own is scary. Hearing it in the game is terrifying, especially when you aren't expecting it.
1.4 also changed a lot of the mob noises, so the skeleton's noise is now considerably more rattly, and the creepers now have a hiss that's somehow worse. Plus their explosion is even louder.
The Witch. While thankfully this new mob only spawns in swamp biomes and in special huts (meaning it can't appear in already rendered ones), it's got terrifying potential, with nausea potions and poison to make fighting it even more difficult, with its 26 hit points. Unfortunately, the opportunity for a Karmic Death is also gone as you can't burn them (they simply drink potions of fire resistance).
Griefers in Minecraft are, without a doubt, the most terrifying type out there. They don't want to help you, or be nice, or anything. They just want to watch the world burn BECAUSE ITS FUNNY TO THEM.
