There's something going on that only you can see or hear. Maybe you have a SpiritAdvisor; maybe there's some magic that only you're aware of. You (or the audience) may even start to [[ThroughTheEyesOfMadness question your sanity]], but you've come to accept that [[WeirdnessCensor nobody else notices this thing]].

Then, someone else does. Naturally, you're incredibly surprised.

[[folder: Anime and Manga ]]

* In the ''Anime/AfroSamurai'' manga, a variation occurs-- no one but Afro can see or hear Ninja Ninja, and in the anime series, he's simply imaginary or a hallucination. When someone comes along that evidently ''can'' see him, [[YouCanSeeMe Ninja Ninja is the one that's surprised]].
* In ''Manga/JoJosBizarreAdventure'', many Stand users are relieved the first time they meet another one, since Stands are [[InvisibleToNormals invisible and intangible to anyone but other users]].
** Heck, this is the way Stands were introduced to the series, with main character Jotaro convinced that he is possessed by an evil spirit, until his grandfather Joseph is called in to explain things.
* In ''NatsumeYuujinchou'', three people say this to the main character, who has always been lonely because in his childhood, [[CassandraTruth no one would believe him when he says he can see]] {{Youkai}}, though only one of then can actually ''see''; the other two can feel their presence and see them under certain circumstances.
** There's a [[TearJerker heartwrenching flashback]] to Natsume's childhood where he is befriended by an older girl who claims to be able to see them too. For the first time in his life, [[YouAreNotAlone he's not alone.]] [[spoiler: Turns out she's a youkai herself, and just took human form so she could get near him.]]
* ''GaRei'''s main character is plagued by spirits. When he meets a girl who is able to see them as well, she promptly recruits him for the government.

* FrankMiller's ''Ronin'' had a variant when a samurai and his lord are by some Buddha statues, having a conversation. Suddenly, the statues suddenly join in on the conversation and the Samurai yelps that the statues are talking. At that, the Lord notes he's glad his retainer heard them too since he didn't want to think he was going senile. As it turns out, the voices were coming from {{Mook}}s who wanted to spook their targets before they ambushed them.

[[folder: Film ]]

* This happens at the end of ''Film/{{Ghost}}''. Oda Mae's the only one who can hear Sam until the White Light appears. Then his girlfriend can hear him, too. And a few seconds later, they can both see him as well.
* In TheFilmOfTheBook ''{{Jumanji}}'':
** Alan thinks he's the only person who can hear the drumming coming from the box, until Sarah shows up and can hear it too.
** Also Carl and Alan exchange looks to make sure they both are seeing monkeys on a motorcycle.
** Also, at one point, Sarah and the kids see a few monkeys go by on a motorcycle. Sarah, who had spent 26 years doubting her sanity, was mildly nonpulsed.
-->'''Sarah:''' You just say three monkeys go by on a motorcycle, right?
-->'''Judy''': (nervously) Yeah....
-->'''Sarah:''' Good girl. Come on.
* In ''Heart & Souls'', Thomas (and the ghosts) are ''very'' surprised to meet someone in the hospital who can see the four souls.
* Played with in ''Film/ABeautifulMind''. After giving a lecture in class, John Nash is greeted in the hall by a man. Before he talks to him, Nash inquires of a passing student if she can see the man. Makes sense, given that he's been given to long-standing hallucinations.

[[folder: Literature ]]

* In the Creator/StephenKing novel ''{{It}}'', the children band together to defeat [[MonsterClown It]] once they realize that only they can see it after talking about it to each other.
* In ''HarryPotterAndTheOrderOfThePhoenix'' Harry's confused when he starts seeing the thestrals when nobody else can. He's less than entirely reassured when Luna tells him that she can see them too, and that he's [[{{Cloudcuckoolander}} just as sane as she is]].
** Later in the book, it's revealed why only a few people can see them: they're only visible to those who have directly witnessed a death. Only three students present at the thestral feeding (Harry, Neville, and a Slytherin student) can see them, as can Hagrid. Umbridge apparently can't.
* In ''[[Literature/TheStormlightArchive The Way Of Kings]]'', by Creator/BrandonSanderson, Kaladin is nearly convinced that the spren talking to him is a sign of insanity...then Rock bows to her.
* In the ''Newsflesh'' series, Shaun has been [[spoiler: hallucinating his dead sister George]] In the third book, when they break into the CDC (again), [[spoiler: they meet up with a clone of George.]] Needless to say, Shaun is ''very'' surprised that Becks and Mahir can also see her. Not that Becks and Mahir take it very well, as their blog entries at the end of the chapter show.

[[folder: Live Action TV ]]

* This happens a few times in ''Series/{{Battlestar Galactica|Reimagined}}'':
** In the finale, [[spoiler:it happens simultaneously to Baltar and Caprica-Six--they each realize that the other one is seeing their SpiritAdvisor head-counterparts.]]
** Earlier, Starbuck shocks the Final Five when she plays "All Along the Watchtower" on the piano, as they had been the only ones who could hear it.
** And in the first season, Baltar enters CIC and is unsurprised to see Head Six there, until the Galactica crew start interacting with her and he realises to his shock that she's another Number Six Cylon, posing as human Shelley Godfrey.
* In ''Series/DueSouth'', the main character constantly sees his father's ghost; eventually, so does a former comrade of his father's.
* In the ''Series/{{Lost}}'' episode "What Kate Did," Kate thinks she's going crazy because she keeps seeing the horse that helped her escape the marshal. Then Sawyer sees it, too.

** Shannon sees an apparition of Walt (who had been kidnapped by the Others) a few times during season two, and Sayid doesn't believe her until he sees him as well.

* ''Series/RandallAndHopkirkDeceased'': Jeff meets a man who's openly skeptical of the existence of ghosts--except it turns out he can see Marty.
* For two and a half seasons of ''SlingsAndArrows'', Geoffrey is the only one who can see [[SpiritAdvisor Oliver]]. Then Oliver makes one of his standard smart remarks to Charles--and Charles answers him back.
* ''NorthernExposure''
** There's an episode where Dr. Fleischman is being troubled by a persistent spirit of some kind (possibly themed around the holiday of Yom Kippur?) and Ed, the shaman-in-training, can see it too.
-->'''Fleischman:''' What does it look like to you?\\
'''Ed:''' Sort of... egg shaped. ''(later)'' Would you like to be alone with your manifestation?
** Also, when they decide to bring back Adam as a recurring character, the one-off joke of only Joel having seen him is ditched, to Joel's amazement (and annoyance when nobody really cares that he was right).
* In the first episode of series 3 of ''AshesToAshes'' DI Alex Drake walks down an alley and sees the world seem to disappear into a giant starfield. She looks away, and when she looks back the world has returned. Given her circumstances, Alex is accustomed to seeing and hearing bizarre phenomenon that no one else will notice. Then Shaz mentions having seen stars. [[spoiler:Then Ray sees them but Chris, who is with him, does not. Later, in the police station Ray and Shaz hear voices, are frightened and reflexively cling to one another in fear as Chris walks in and -- not hearing those voices -- draws the wrong conclusion. And then, finally, Chris sees the stars while walking with Ray and Shaz (who see them also to confirm that he is not crazy, invoking this trope instantly), and he now seems to have taken on the same extra-awareness as the others. ]]
* In ''{{Fringe}}'', after [[spoiler: Peter is erased from history]], this is Walter Bishop's reaction to Olivia seeing [[spoiler: Peter]] in her dreams, as Walter had been hearing his voice and seeing him in mirrors. Just in time, too: [[spoiler: it happens when Walter is about to attempt a lobotomy on himself.]]
* In ''DoctorWho'', the Master is plagued by the [[TerribleTicking the sound of drums]], something that the Doctor dismisses as just his insanity. The Master eventually has enough and performs a MindMeld, which causes the Doctor to visibly freak out when he realises that he can hear them ''too''.
* In the second season of "{{Grimm}}" Nick says this to Hank to reassure him he's not going insane and that he too can see wesen. (Hank was about to shoot his goddaughter Carly, who from his perpesctive had just become a horrifying flesh-eating monster.)

[[folder: Video Games ]]

* During the ''VideoGame/AnotherCode'' games, Ashley is normally the only one who can see ghosts, but she encounters three people who can do the same as well. It becomes important to two plots as [[spoiler:seeing D is what startles Bill into his DisneyVillainDeath and seeing his sister resolves part of Matt's subplot.]] As for Captain, it's more of a surprise to all parties.
* Played with in the ''SamAndMax'' game episode ''The Penal Zone'': Harry Moleman thinks he is the only one who sees [[spoiler: the ghost of Momma Bosco]], and wants to capitalize this ability for profit. Turns out that it is not a special ability at all.
