* Sendoff Spring. The hidden fourth lake of Sinnoh, it's small, isolated and the only significant feature is a pier that extends from the top of the cliff over the lake, not from the shore of the lake itself. Given that, the name and the map description saying that it was 'kept secret', the overall impression is that this is a place where people go to kill themselves.

** The Distortion World, Giratina's domain away from the human realm. Described as a realm opposite the real world, it's a place without rules, light or logic, where [[AlienGeometries landmasses simply float in the air and waterfalls float upwards]], with a large, dark void always beneath your feet as the player has to traverse it towards Cyrus and Giratina. Not only do you have to go through this place devoid of life with that [[https://www.youtube.com/watch?v=_FOQK2M9jAo disturbing music]] in the background, you will sometimes see Giratina's Origin Forme flying fast in the background, always close to you, waiting for the moment when you'll inevitably have to fight it.

* The [[HauntedHouse Old Chateau]], scary to the point that the nearest Gym Leader refuses to set foot there. This place is haunted not just by ghost-type Pokémon, ''but by human ghosts too.'' There's also a painting with glowing red eyes that follow you around. The [[https://www.youtube.com/watch?v=tb4yEQ4AZ3E background music that plays when inside the Chateau]] is also perhaps one of the scariest pieces of music in the whole franchise. Oh, and it’s also the location of the Ghost Pokémon Rotom.

* The laboratory in the Galactic Veilstone Building, with creepy music, vats with ambiguous objects floating in them, and scientists who put the Lake Trio through such pain to create the Red Chain that [[EvenEvilHasStandards even they feel awful about it, and secretly begin to question Cyrus's goals]].

** Its infamous appearance in ''Platinum'', when Cyrus' plan and the Lake Trio's interference awakens it at the Spear Pillar. It emerges from a pitch-black hole in the ground, its [[RedEyesTakeWarning eyes glowing a deep, sinister red]], ''actual darkness'' dripping from its shadowy figure on the ground. It's such a big moment that [[HorrifyingTheHorror even Dialga and Palkia have to step back]]. It extends its wings, which reshape into what seems to be claws ready to strike, [[PsychoticSmirk smiles]] [[TheFourthWallWillNotProtectYou at the player]]... then leaps [[JumpScare RIGHT AT THE SCREEN]]!

** In ''Brilliant Diamond and Shining Pearl'', while Giratina is still located and catchable in Turnback Cave, an uncatchable BonusBoss is located in Ramanas Park's Distortion Room, which is physically a [[EldritchLocation one room-sized match for the Distortion World]] and inexplicably has you walking on the ceiling. Awakening the Origin Forme Giratina there will summon a shadowy Level ''100'' version of it.

** The Hall of Origin. A pocket dimension sitting right above the Spear Pillar, inaccessible in-game without [[https://bulbapedia.bulbagarden.net/wiki/Pal_Park_Retire_glitch major DP-only glitches]], since the key item to access it was never officially released. Regardless, playing the Azure Flute at the entrance of the Spear Pillar lets you access the towering mythical staircase leading to the Hall, where it's only you and the "Original One". The place is eerie and off-putting, compounded by a [[https://www.youtube.com/watch?v=y-HFTjzXF_g disturbing track]] as you approach Arceus. It's actually the first section of the game's opening in reverse.

* Encountering a roaming legendary can be this. In the postgame, there can be up to ''five'' legendaries roaming the region. Unless you stick to the [[PostEndGameContent Battle Zone]] where they don’t appear, or specifically avoid them using the map on your Pokétch, you can encounter them unknowingly at any time. All except Cresselia have a different battle theme than regular wild Pokémon, [[JumpScare which can be give you quite the shock while you’re just walking around]].

* The Dark-type Pokémon Darkrai is literal [[NightmareFuel Nightmare Fuel]]. It is said to give people and Pokémon around it nightmares, although some of its Dex entries state that it’s a defense mechanism. Its ability, Bad Dreams, drains the health of sleeping Pokémon.
