-->-- ''Series/{{Being Human|UK}}'', pilot episode

Someone is invisible or otherwise [[TheMasquerade magically disguised]]. At some point, they notice they're attracting an unexpected amount of attention for someone who shouldn't be attracting ''any''. "You Can See Me?" The standard response is some variant of "Why wouldn't I be able to see you?" or, more succinctly, "Well, ''duh''."

Usually happens one of three ways. An [[InvisibleToNormals invisible]] character, either despondent of being invisible or overconfident in same, runs into someone who can perceive them in some way or another (infrared sight, anti-magic glasses, etc.). Another involves supernaturals under some kind of glamour, or simply InvisibleToNormals, and saying this when they experience GlamourFailure at the [[strike:hands]] eyes of someone who can see through their deception. The last way, almost always PlayedForLaughs, is that the person was never invisible or disguised in the first place; they just thought they were.

In any case, it is pretty much inevitable that any character in this situation will say this line (instead of, say, figuring that if the person is talking to them and looking at them they can probably see them) even though it makes them sound ridiculous and ruins any attempt to pretend to be normal.
Savvier invisible people will actually phrase the question such that they aren't asking ''if'' but ''how''. If one of TheFairFolk asks you "Which eye do you see me with?" be assured whatever eye you say is going to be rendered blind.

If the invisible person can only be seen under unusual circumstances, it could be a case of ByTheEyesOfTheBlind. Also compare ISeeThemToo and ISeeDeadPeople. Now, if this happens in combat the invisible person is much likelier to say "OhCrap."

Not related to Wrestling/JohnCena's CatchPhrase ("You Can't See Me"). Although [[CaptainObvious people ]]''[[CaptainObvious can]]'' [[CaptainObvious see him, obviously]].


[[folder:Anime & Manga]]
* ''Manga/{{Bleach}}'':
** Rukia's reaction when Ichigo addresses her in the first chapter of the manga. Ichigo takes this a step further, and ''kicks'' her when she apparently tries to break into his home.
** And in a slightly stranger example, Ichigo's reaction when Tatsuki asks what his "Deputy Soul Reaper" badge is, which was stated to be InvisibleToNormals.
* Ryuk in ''Manga/DeathNote'' says this to a criminal who inadvertently touched a piece of the title ArtifactOfDoom as one of Light's gambits, which enables the criminal to see the death note's shinigami prior owner and causes him to freak out.
* The way Cain and [[BattleButler Riff]] first met in ''Manga/{{Godchild}}''. Cain wasn't actually invisible -- it's just all the household servants had been given strict orders to act as if he was all his life, and he hadn't been allowed out much. [[AbusiveParents Inventive of Alexis, no?]] Turns out the reason Riff hadn't been given the same instructions wasn't because he was not-exactly-a-servant, but because [[spoiler:Alexis was setting him up to become Cain's number-one person in the world, so he could take him away again by activating his suppressed evil personality from before he was a zombie.]] Just to screw with the kid.
* In ''Manga/FightIppatsuJuudenChan'', Charger Girls use a cloaking system to hide themselves from the populace of Earth (normally, they're transparent, but can still be seen). This system also makes them intangible. However, for some reason, this cloaking system has absolutely no effect on Sento. Which Plug discovers via a baseball bat to the head when she assumes Sento can't possibly be referring to her. Alastar makes the same discovery in a similar manner.
* In ''Manga/HoneyCrush'', this is said by the ghost Mitsu when she discovers that Kyouko has [[ISeeDeadPeople the ability to see ghosts]].
* Happens in ''Manga/InuYasha'' with invisibility magic that wears off without the user noticing.
* ''Manga/SgtFrog'' starts with Natsumi pointing a hidden Keroro out to Fuyuki, prompting Keroro to drop his disguise and ask this. Doubly funny because she ''didn't'' see him; she was just pointing in a random direction that Keroro ''happened'' to be in. [[HilarityEnsues Hilarity (and a whole show) Ensues]].
* In the first episode of ''Anime/ALittleSnowFairySugar'', Sugar has this reaction when she notices Saga staring intensely at her.
* Also applies to the overall reaction Sayo has when someone sees her in ''Manga/MahouSenseiNegima''. Especially the first time.
* The first episode of ''Manga/NininGaShinobuden'' has Shinobu attempting to sneak into Kaede's house by making herself invisible. She fails miserably. Twice.
* Amidamaru to [[spoiler:Ryu]] in ''Manga/ShamanKing'' when discovering his shaman abilities.
* ''Manga/UshioToTora'':
** One arc has the BigBad send his minions to eat everyone's memories of the protagonist Ushio: his friends and the people he's saved have zero clue who he is, leading to the most heartening moments in the series when it turns out Tora wasn't affected.
* Happens early in ''Manga/YuYuHakusho'', right before [[spoiler:Botan reveals herself to Yusuke the second time.]] Yusuke caught the
little demon bare-handed, and this was his general reaction.

[[folder:Comic Books]]
* Subverted in ''ComicBook/TheBooksOfMagic'', where the answer to that question was, "Of course I can't see you. I can't hear you either." He wasn't lying. The explanation: [[spoiler:Tim Hunter and ComicBook/{{the Phantom Stranger}} have gone back in time, invisibly, to meet an Atlantean sorcerer. The sorcerer can't detect them directly in any way, but his magic tells him they're there, and what they say.]]
* Played with in ''ComicBook/IdentityCrisis'': in one scene, Flash is vibrating rapidly so he can sit in on a meeting unseen, but Hawkman can still see him (because "his eyes can see a hummingbird's wings flap", or something). Green Arrow then asks Green Lantern to come out too, and when GL asks how GA could see him, GA says [[YouJustToldMe he just guessed]].
* In ''ComicBook/TheLeagueOfExtraordinaryGentlemen'', Mr. Hyde reveals his ability to see by way of heat signatures to The Invisible Man (but not the audience, who knew since their first meeting) shortly before [[spoiler:Hyde rapes him to death.]]
* In ''[[Comicbook/{{Supergirl 2005}} a Post-Crisis]]'' ''Comicbook/{{Supergirl}}'' issue, a villain called the Calculator is monitoring Kara under Comicbook/LexLuthor's orders. At one point, she glares straight in the direction of the Calculator’s camera, which is enough for him to freak out in a SpitTake because he realizes that she can see him even though it was supposedly impossible.
* In the ''ComicBook/YoungJustice'' "Sins of Youth" crossover, Deadman (now de-aged to about 10) can be seen by Secret (now aged to mid-twenties).
* At the end of ''ComicBook/BlackestNight,'' Deadman is freaked out to learn that ''everyone'' can see him -- because he's not dead anymore.
* In ''ComicBook/KingdomCome,'' the Spectre has brought Norman to witness a Justice League meeting. They're in the astral plane, and thus nominally invisible to the heroes -- except for the Flash, whose permanent vibrations mean he sees several layers of reality at once.

[[folder:Fan Works]]
* Canada of ''Manga/AxisPowersHetalia'' does this in ''nearly any fic'' that has him as the romantic counterpart to any more prominent character.
* Ranma not only says this whenever anyone reveals they can see his cursed form in the ''Manga/RanmaOneHalf'' fanfic ''A Different Curse'', he also hastily covers "his" breasts and crotch. Given that in this fanfic, he is nude in his cursed form (a female spirit, not only {{invisible to normals}}, but intangible to any non-living material), this reaction is probably justified.
* In ''Fanfic/KyonBigDamnHero'', [[VisualNovel/HigurashiWhenTheyCry Hanyuu]] is surprised when Yuki can not only see but also touch her.
* In the first chapter of the ''Rise Of The Guardians'' fic, [[https://www.fanfiction.net/s/8729513/1/How-to-Make-a-Believer-Believe How To Make A Believer Believe,]] this is used rather humorously.
* In ''Fanfic/PokemonBlackandWhiteTaleofaLegend'', Victini follows Volantes around mostly undetected -but the young man, spiritual successor to Victini's old friend, the White Hero, notices somebody else has joined the party.

[[folder:Films -- Animation]]
* Near the climax of ''WesternAnimation/RiseOfTheGuardians'' [[spoiler: Jack Frost restores Jamie's belief in the Easter Bunny, and in doing so, causes Jamie to believe in him. Because Jack is now a Guardian, [[ClapYourHandsIfYouBelieve this belief allows Jamie to see him, which is the first time in 300 years anyone human has seen Jack]].]]

[[folder:Films -- Live-Action]]
* In ''Abbott & Costello Meet the Invisible Man'', when a shower is turned on, the invisible man can be seen enough to be stabbed by a thrown knife.
* Lydia to the Maitlands in ''Film/{{Beetlejuice}}''.
* Harry Potter in ''Film/EpicMovie'': "You can't see me. I'm invisible."
* In ''Film/ErikTheViking'', Erik charges into battle with a rag on his head, which he had previously used to make himself invisible to his lover's father. What he doesn't realise is that the rag only makes him invisible to ''that one guy''. So instead of an invisible warrior, he's actually an unnervingly confident guy with a dishcloth on his head. After winning the battle single-handedly he discovers he was visible the whole time, and promptly faints.
* In ''Film/GhostTown'', this is the ghosts' initial reaction to Pincus.
* In ''Film/GrandmasBoy2006'', JP attempts to hide against a wall behind his trenchcoat, unsuccessfully, '''after talking'''.
-->'''JP:''' (''Robot Voice to Alex walking away'') I hate your face.\\
'''Alex:''' (''pauses, turns around'') Did you say something?\\
(''JP hides behind his coat'')\\
'''Alex:''' You're fuckin' weird.\\
'''JP:''' ...How did he see me?
* A female troll says this to Film/{{Hellboy}} et al. when they see through her glamor using magical lenses. However, the audience can also only see her as nonhuman when someone's looking through the lenses -- leading to a rather amusing scene of Hellboy [[spoiler:punching an old woman across the room.]]
* Averted in ''Film/JustLikeHeaven''. Elizabeth discovers David can see her before discovering no one else can.
* In ''Susie Q'', only Zach can see Susie, [[spoiler: a ghost who died forty years earlier, because he's in possession of the bracelet she wore when she died.]]
* In the "Son of the Invisible Man" segment of ''Film/AmazonWomenOnTheMoon'', Ed Begley Jr. is running around naked while the jaded villagers just humor him.
* Played for drama (if not horror) in ''Film/JusticeLeague2017'': A freshly-resurrected Superman is intent on killing Batman. Wonder Woman and Aquaman both rush up to stop him, the Flash runs up behind... and as he approaches in slo-mo BulletTime, we see Superman's ''tracking him''. Cut back to Flash's look of horror, cut back to Superman turning to face Flash, still in BulletTime.

* In Allison Croggon's ''The Books of Pellinor'' series, the main characters meet in the first chapter like this. The male lead Cadvan, a bard, is hiding under a glimmer spell that is supposed to make him invisible. He tries to find shelter in a stable at a slave settlement to rest, but the protagonist Mearad sees him because she too is a bard. Her having the Voice is the main reason she is taken with him when he leaves.
* In ''Literature/ShamanOfTheUndead'' this happens twice when Ida, a medium, talks with ghosts. In first case they were both surprised and reaction was something like "Nobody else can?!", but in second, when she's already trained, her only reaction is a shrug and "Sure I can."
* In ''Literature/CleverPollyAndTheStupidWolf'', the Wolf thinks he's made himself invisible and has tested it by acting outrageously in public. Naturally, people have been shocked by the mysterious sounds coming from nowhere... right? Polly eventually persuades him he is visible, and he sneaks away in shame without eating her.
* Also, in the ''Franchise/StarWarsExpandedUniverse'' novel ''Dark Apprentice'', when Luke is turned into an invisible Force Ghost, only his (toddler) niece and nephew can see him.
* Happens a lot in ''Literature/{{Discworld}}'', especially when Death is seen by children (who lack a WeirdnessCensor). And the wizards, who are specially trained to see what is really there.
** Played for humor in ''Discworld/{{Mort}}''.
--->''Mort tapped the stallholder in the small of the back. "Can you see me?" he demanded. The stallholder squinted critically at him. "I reckon so," he said, "or someone very much like you." "Thank you," said Mort, immensely relieved. "Don't mention it. I see lots of people every day, no charge. Want to buy some bootlaces?"''
** In ''Discworld/WyrdSisters'', the WeirdnessCensor breaks down under the overriding power of ClapYourHandsIfYouBelieve. Death ends up taking the stage in place of an actor whose role was Death. So the hundred or so live audience members watching the stage all expect to see Death appear, and consequently, ''they all see him.'' Death is so unnerved by this that he gets stage fright.
* In ''Literature/OnAPaleHorse'', the newly-appointed Incarnation of Death is surprised to find some mortals can see him for who he is --- usually those who are sincerely religious, or who have a deep connection to the one about to die. Most people see and hear something else when Death is there.
* Creator/PeterSBeagle's ''Literature/TheLastUnicorn'':
** The Unicorn goes almost unrecognized in her travels, as decades of unbelief cause people to see her as a horse. Only a handful of marginalized people, those who are themselves more than they seem, can truly see her -- and of course [[BigBad King Haggard]] and his [[TheDragon Red Bull]], who are not subject to illusions.
** The unicorn's companions, especially Schmendrick, also appear as less than they really are. Captain Cully and the people of Hagsgate have the opposite problem. Prince Lir, on the other hand, always looks exactly like what he is -- and yet, being TheHero, he's more guided by myth than any of the others.
* Happens several times with the various ghosts in ''Literature/TheMediator'' series by Creator/MegCabot. As evidenced by Suze's [[DeadpanSnarker nonchalant and highly uninterested]] reaction when Jesse pulls this, this happens ''a lot''.
* ''Literature/PercyJacksonAndTheOlympians'': Percy's quite surprised when Rachael can see both his sword and the skeletal warriors chasing him. Though the line is more "You can see them?"
* In ''Things Not Seen'' by Andrew Clements, the main character Bobby does one of these towards the end of the book.
* ''Literature/SwordOfTruth'' series:
** Kahlan's first encounter with the Pristinely Ungifted after [[spoiler:the Chainfire Event.]] She may not have said it, but she was certainly surprised. Further, the spell in question was corrupted [[spoiler:by the Chimes]], so some normal people weren't affected. Jagang realized this, and to find those people, has her ''walk naked through his camp''. The people who saw the beautiful, naked women and tried to grab her were caught by Jagang's troops and conscripted to guard Kahlan.
** In a curious inversion, Adie is blind but sees using magic. She encounters a pristinely ungifted person, and she hears them but can't see them, and is thoroughly disturbed.
* Literature/CiaphasCain once encounters a psyker assassin who can turn invisible. However, he got his powers recently through AppliedPhlebotinum, so he doesn't master them enough to avoid InvisibilityFlicker, and thus Cain can still defend against him. Instead of the usual reaction, the assassin is more whiny that his power trip is interrupted than disturbed, not helped by Cain snarking until [[AntiMagic Jurgen]] arrives.
* The third ''VideoGame/{{Myst}}'' book, ''The Book of D'ni'', has an interesting inversion, with a character from distant offshoot of the D'ni asking if he could see our protagonists. [[spoiler:Turns out his society is built on massive amounts of slave labor and they have conditioned themselves to not see the slaves anymore. He wasn't sure if Atrus and co. were slaves.]]
* In the ''Literature/TowersTrilogy'', the ghost Shai is surprised when Wen can see her, not realizing that Wen is also a ghost.

[[folder:Live-Action TV]]
* ''Series/{{Being Human|UK}}'':
** Annie is so astonished to be seen, she asks twice and waves her arms around for good measure.
** Subverted in Series 1, Episode 4: a woman replies to what she says, which triggers the question. Subverted in that the woman is ''blind,'' thus can't technically ''see'' Annie. But she seems to hear her just fine, which most people can't either.
** Happens again when Annie meets a psychic in Series 2, Episode 6.
* ''Series/BuffyTheVampireSlayer'':
** Xander in the 4th season Halloween episode, "Fear Itself", on becoming visible/audible again, asks not only "You can see me?" but "You can hear me?" too.
** Also applicable in an odd way during the fifth season when [[spoiler:Only the insane can see that Dawn is the Key]].
* Subverted interestingly in the ''Series/DoctorWho'' episode [[Recap/DoctorWhoS29E10Blink "Blink"]]. Sally is shocked when the Doctor appears to be responding to her from a recording made in 1969. He can't actually see or hear her; he's [[TheTapeKnewYouWouldSayThat reading from a transcript made of the conversation]] when Sally had the conversation forty years later... [[TimeyWimeyBall it's complicated.]]
* Occurs at least once in ''Series/DueSouth'' with Fraser and his father. Possibly twice, because Fraser discovered two other people who could see Bob-Bob's best friend Buck Frobisher and Ben's half sister/Bob's daughter Maggie.
* A ghost woman in some episode of ''Series/{{Farscape}}'' is surprised that Stark can see her, as she was desperately trying to interact with people. Stark quickly points out that he's the only one on board with this ability.
* In ''Series/{{Grimm}}'', many [[OurMonstersAreDifferent Wesen]] have a serious OhCrap moment when they realise that Nick is capable of noticing their GlamourFailure, since [[TheDreaded the Grimm]] are the monsters that ''they'' tell their kids scary stories about.
* ''Series/TheHauntedHathaways'':
** In Haunted Thundermans, Louie (ghosts can't be seen or heard except by their friends) walks out past the Thundermans, unaware that Nora, Billy and Phoebe are tracking his movement. Then Nora speaks to him and he freaks out, which get Miles involved and then Billy immediately waves hello. All superhumans can see ghosts.
** After an accident with a ghostbusting staff, Meadow gains this ability and triggers another Louie freakout when she asks who he is.
* ''Series/{{Heroes}}'': Claude's introduction to Peter. "YUH CAN SEE MEH?!" He even gets personal about it. "NO ONE SEES ME!"
* Another short-lived sitcom, ''Jennifer Slept Here'', was about the ghost of an old-time movie star who is visible to the son of the family who moves into her house. She decides she's here to turn him from GeekToChic.
* The short-lived sitcom ''Nearly Departed'', about a couple haunting their old house. The pilot has the husband mocking the home's new residents relentlessly, as they can't see him. When he's left alone in the main room with the elderly grandfather, he continues to mock the man until Grandpa yells at him to shut up. After delivering the stock phrase of this trope, Grandpa explains he didn't mention to the rest of the family because "at my age, when you start seeing things they put you in a home".
* In the series ''Series/{{Psych}}'', Juliet O'Hara receives a phone call from 'psychic' Shawn Spencer. He teases her by listing every detail about what she was doing, before revealing that he was simply sitting in the Chief's office, a mere twenty feet away. Somewhat referenced by Shawn in that he says, "Notice how no one ever looks in here? What is it that you're afraid of?" Also contains ICanSeeYou.
* Children and the mentally ill can see Al in ''Series/QuantumLeap.'' He never says the trope name, but his OhCrap looks are definitely this trope.
** Also one episode with a Scrooge-like character who for some strange coincidence could see Al (his brainwaves were similar to the main character's or some bunk). Obviously, this leads to some confusion, and also to the visit of the three ghosts of Christmas...
* Both versions of ''Series/RandallAndHopkirkDeceased'' has this when someone could see Marty, as he is a [[OurGhostsAreDifferent ghost]] who can usually [[SpiritAdvisor only be seen by his partner Jeff]]. For example, when the psychic Mrs. Pleasance spots him in "For The Girl Who Has Everything".
* ''Series/SabrinaTheTeenageWitch'': Sabrina once turned a classmate invisible and spent most of the rest of the episode trying to find his exact spot to turn him visible again. He'd pretty much gotten used to invisibility when she finally succeeded and Zelda saw him. When he said the phrase, she replied, "Yes, and I can see that you're [[LessDisturbingInContext not wearing pants]]."
* The above twist was also used in ''Series/SevenDays,'' when Frank becomes invisible but can be heard by a BlindBlackGuy.
* Burt Campbell in ''Series/{{Soap}}'' thought he could become invisible for a while. At one point he tried to show his wife but she could still see him; he decided that was because he was wet (they were in the bathtub together).
* ''Series/StargateSG1''
** Occurs in the episode "Crystal Skull", in which Daniel Jackson has been turned invisible by one of the phlebotinum skulls. Daniel's grandfather, Nick, can see him because of an encounter ''he'' had with a skull, but dismisses Daniel as a hallucination. It's not until well into the episode that Daniel realizes he's visible to Nick and uses him to communicate with the rest of the SG-1 team.
** Occurs again in a later season when Cam, trapped in another dimension, is talking to Teal'c, who has just used an alien device that makes the user invisible. Teal'c takes it in stride, always ready for combat, as Cam struggles with the revelation.
** Despite seemingly recycling plots in such a manner throughout the series, the writers were always quick to hang a lampshade and reference the earlier episodes' events, often even using Cam's memorization of mission reports. The show even lampshaded this itself in its lampshade-heavy fanservice 200th episode.
* ''Series/StarTrekTheNextGeneration''. In "The Next Phase", the episode where Geordi [=LaForge=] and Ensign Ro are made "out of phase" by an accident on board a Romulan Warbird, Ro enters a room and is surprised to see a Romulan pointing a disrupter at her. She automatically turns to look behind her (as only Geordi had been able to see her up til now) but the Romulan says, "Yes, I can see you." It turns out he too is out of phase.
* Another Marty had a similar reaction, for similar reasons, in ''Series/TeenAngel'' when he met an old lady who could see him because [[spoiler:she was soon to die]].
* The "Weird Superheroes" game on ''Series/WhoseLineIsItAnyway'' throws out the name "Think's He's Invisible Man". And gives it to Tony Slattery. [[HilarityEnsues Hilarity guaranteed to ensue.]]
* Played with in ''Series/BattlestarGalactica2003''. Baltar can occasionally see an "invisible" Cylon Six. In ''Six Degrees of Separation'', he encounters a ''real'' Cylon Six on ''Galactica'' and mistakes her for the invisible one. When he realizes that everyone can see her, he repeatedly says "You can see her?" and Colonel Tigh deadpans "she's right beside you".
* In one episode of ''Series/GetSmart'', K.A.O.S. was carrying out a scheme to (falsely) convince Max they had access to an Invisibility Ray. In the end they capture him, and Max "uses" the ray on himself. The K.A.O.S. agents go along with it briefly to maintain the ruse, but then 99 is brought in having no idea what is going on, and Max confuses himself about who can see what.
* In the ''Series/{{Sliders}}'' episode "Gillian of the Spirits", one of the main characters is stuck on another dimensional plane and rendering himself invisible to everyone but a girl named Gillian, who has the ability to see supernatural phenomena.
* Done as a prank on ''Series/NYPDBlue''. The perp has visited a Santaria priest to get a spell where he becomes invisible to police. Martinez and Medevoy pretend they can't see him in the interview room, so he starts to sneak out. Then Martinez stops him.
* ''Series/{{Supernatural}}''. Played for a HopeSpot in "Party On, Garth". After a number of odd events, Sam and Dean have a long discussion over whether the ghost of Bobby Singer is helping them. They eventually conclude it's wishful thinking on their part and leave the room. Then camera then pans over to reveal Bobby's ghost. Suddenly Dean says HeyWait and rushes back inside.
-->'''Dean:''' ''(looking directly at Bobby)'' There you are!
-->''(Bobby smiles...until Dean picks up a hip flask he left behind and walks out)''
-->'''Bobby:''' I'm right here, you [[CatchPhrase idgit!]]
* ''Series/TheMagicians2016'' has a mutual example in "Be The Penny" when two people who are trapped on the Astral Plane meet each other and both say this.

[[folder:Tabletop Games]]
* This is also true in White Wolf's ''TabletopGame/ChangelingTheDreaming''. Children generally believe anything they see, whereas adults rationalize and have a WeirdnessCensor. And the mentally ill/insane's WeirdnessCensor is broken or gone.
* ''TabletopGame/GeistTheSinEaters'': Sin-Eaters hear this one a lot. Not only can [[ISeeDeadPeople they see dead people]], ghosts will quickly ping to the fact that they're being observed and know that it's the Sin-Eater doing it. Sometimes Sin-Eaters have to suppress their ghost sight if they want to make it down the street undisturbed.
* And in ''TabletopGame/VampireTheMasquerade'' the vampiric discipline "Obfuscate" is a subversion, the subversion being a quirk of the ability that both characters and players themselves may not be aware of. Obfuscate does indeed make one invisible to anyone looking at you (unless they have Auspex or other supernatural means of detecting someone) but it's not actual invisibility, it's a ''mind trick.'' Also it's harder to use if you're actively being watched. Cameras and such will still capture images of someone under Obfuscate. This encourages players to perform the old "Turn a corner and when they follow, I'm not there" trick.

[[folder:Video Games]]
* Fairies in ''VideoGame/DragonQuestV'' can normally only seen by innocent children. As a child, the fairy named Honey takes you to solve her world's problem because nobody else could see her. When you're an adult and are heading into a fairy wood, you can no longer see any fairies. It's your two kids that locate them. Once you're actually in their realm you can see them just fine, though.
* [[WizardingSchool The College Of Winterhold]] in ''VideoGame/TheElderScrollsVSkyrim'' has Drevis Neloren, an instructor in and the master trainer of the Illusion school of magic, where you can find the invisibility spell. The player character's first interaction with him has Drevis asking if you can see him, and you can answer either yes or no. If you say no, he mentions that you still shouldn't be able to hear him, and that there's something wrong with his spell. The silence and invisibility effects are separated in-game, though, so possibly he was trying to combine the two.
* In ''VideoGame/TheLegendOfZeldaSpiritTracks'', Zelda ask this question when she finally finds the one (hylian) person in all of Hyrule who can see her spirit: [[TheHero Link]]! Being a HeroicMime, Link's answer is reduced to a short nod.
** In ''VideoGame/TheLegendOfZeldaMajorasMask'', you can meet a soldier who has this reaction when you talk with him. The catch is that he is ''actually'' invisible, and to see him you need the [[SeeThruSpecs Lens of Truth]].
* In ''VideoGame/MedievalIITotalWar'', select an enemy assassin sometime and see what they have to say. Namely, north-eastern European nations (such as Denmark) and their associated assassins. "What do you mean you can see me?"
* In the ''VideoGame/MegaManStarForce'' games, the world is full of invisible Wave Beings, and Geo's Visualizer makes him the only human who can see them. Naturally, they tend to be surprised when he addresses them.
* A variant happens in ''VideoGame/{{Portal 2}}''. Wheatley, who normally speaks with a British accent, somehow got the idea that [=GLaDOS=] can't hear him if he speaks with an exaggerated American accent; she disillusions him.
-->'''Wheatley:''' Hey, buddy! I'm speakin' in an accent that is beyond her range of hearin'. I know I'm early but we have to go right now! Walk casually towards my position and we'll go shut her down.
-->'''[=GLaDOS=]:''' ''(audibly exasperated)'' Look, metal ball... I ''can'' hear you.
-->'''Wheatley:''' ''(in his normal voice)'' [[OhCrap Run! I don't need to do the voice, RUN!]]
* The ''VideoGame/{{Thief}}'' series begins with a young Garrett (the player character) trying to pickpocket a Keeper. The Keeper notes that it's not easy to see a Keeper, especially one who does not wish to be seen. This gets a {{Book End|s}} later in the series.
* A not uncommon phrase uttered by Rogue players (and by extension presumably stealthed cat form druids) in ''VideoGame/WorldOfWarcraft'' when discovered by other players. Most common on RP severs.
* In ''[[VideoGame/AnotherCode Trace Memory]]'', when Ashley first meets D, he asks her whether she can actually see him. When she insists that she can, he's not so much surprised as he is delighted: she's the first person who's been able to see him in ''57 years'', and he believes she can help him recover his memories so [[CantMoveOn he can move on]].
* Mandrakes in ''VideoGame/DawnOfWar'': Soulstorm have two variations: they can hiss "[[PreMortemOneLiner Now you see me!]]" when told to attack or or panic "They see us!" when their morale is broken.
* ''VideoGame/MurderedSoulSuspect'': When the recently dead Ronan catches up with Joy, he tries to use his possess/mind read trick on her to find out more information on his killer. He's more than a bit surprised when Joy resists and starts yelling at him for it, and the two trade barbs for a few seconds until Ronan's brain (or whatever it is that make ghosts tick) catches up with his mouth and realizes that she ''can see and hear him''.
-->'''Ronan''': Holy shit, you're a medium.
* ''VideoGame/Bayonetta2'': Loki is surprised that Bayonetta can see him. She explains to him that they are both in Purgatorio, which is why they are able to see each other.
* In ''VideoGame/DarkSoulsI'', Quelana asks this to you when you speak to her for the first time, and with good reason, since you can't see her without a Pyromancy Flame upgraded to at least +10. [[spoiler:Sadly, this is why Laurentius ends up going Hollow when you point him towards her, as his Flame is only at +8, which means he just wandered aimlessly around the area for Gwyn knows how long, unable to see her despite being practically right next to her, until he eventually lost the will to keep going]].

[[folder:Web Comics]]
* In ''Webcomic/TheAdventuresOfShanShan'', both [[http://shanshan.upperrealms.com/view.php?pageid=026&chapterid=1 the lion]] and [[http://shanshan.upperrealms.com/view.php?pageid=025&chapterid=1 Julius]] comment on it.
* ''Webcomic/BobAndGeorge''. All the time. In fact, it almost becomes a running gag that invisible characters can't be seen by their friends, but can be seen by their enemies.
* ''Webcomic/{{Comc}}'' has Block, a FourthWallObserver who cannot be noticed by those who aren't. He utters the trope name when one of the main characters (who normally shouldn't be able to notice him) not only sees him, but straight-up [[https://sites.google.com/site/comccomic/archive/comc28 flirts with him.]] [[spoiler:Sadly for Block, she's actually the author playing a mean prank on him.]]
* Ito, God of Trust and Betrayal from ''Webcomic/AMomentOfPeace'', is thrown off his game when Evi's worm-companion George catches Ito stealing her dreams.
* ''Webcomic/TheOrderOfTheStick'' has it, with Roy as [[spoiler:a ghost]] and the kobold oracle, who makes a remark concerning Roy's mother. After Roy asks why he hadn't told him before, the oracle answers, "I don't know, because I don't like you?"
* In ''Webcomic/SpareKeysForStrangeDoors'', when [[http://sparekeyscomic.com/index.php?comic=20110818 Andrew Cole meets Toby Hathaway.]]
* Played with in ''Webcomic/GirlGenius''. During a [[MidBattleTeaBreak mid-adventure tea break]] with Zeetha, [[TooDumbToFool Bangladesh DuPree]] can't see the hidden [[McNinja Smoke Knight]] Violetta, but she sure can tell she's here, on the seemingly empty chair.
-->'''Bang:''' That's really amazing -- but whatever it is you're doing, ''knock it off''.\\
'''Violetta:''' Whoa. You could ''see'' me?\\
'''Bang:''' No. And it was giving me a ''headache''.
* ''Webcomic/ChildrenOfEldair'': While watching the ceremony granting the girls the Goddess' blessing as an AstralProjection, Koe is surprised when the Goddess turns to him and offers him her blessing as well.
* ''Webcomic/QuestionableContent'': In her first encounter with Internet-enabled RobotGirl Momo, May, who at the time was an AugmentedReality construct displayed in Dale's Google Glasses, is surprised that Momo can see her too, which means her avatar and location are public rather than restricted to Dale's Google account.

* ''WebAnimation/{{Dreamscape}}'': In "Over and Under", Jenna's Skull Snake spots CHEN and Dylan's invisibilty cloak due to its thermal vision. Dylan and CHEN try to fake it by standing still, but the jig is up when Jenna grabs Dylan and gets thrown backwards by CHEN.

[[folder:Western Animation]]
* In the ''WesternAnimation/AdventureTime'' episode "Beyond This Earthly Realm", Finn gets trapped in the "spirit realm" by a magical lamb statue and has to rely on the help of [[FriendlyEnemy the Ice King]], who with his "wizard eyes" is the only one who can see or hear Finn.
* ''WesternAnimation/AquaTeenHungerForce'' (or rather, the Dr. Weird segment before an episode of the show proper) pulls this off to rather hilarious effect:
-->'''Dr. Weird:''' AM I NOT INVISIBLE?!?!\\
'''Steve:''' ... Uh, no sir.\\
'''Dr. Weird:''' '''WHY NOT?!?!?!'''
* A variation in ''WesternAnimation/InvaderZim'': Zim gets a "Megadoomer" mech (by mistake), and stomps over to Dib's house; the Megadoomer makes itself invisible, but...
-->'''Zim:''' I've put up with you long enough, Dib! Now, fight me, an enemy you cannot see!\\
'''Dib:''' You're right there!\\
'''Zim:''' What?!\\
'''Dib:''' There! Your mighty Irken cloaking device cloaks the robot but not you!\\
'''Zim:''' Lies! Now, behold the doom cannon!\\
'''Dib:''' I can't, it's invisible!\\
'''Zim:''' But you can see me?\\
'''Dib:''' That's what I said.\\
'''Zim:''' Oh, that's stupid!\\
'''Dib:''' Really stupid!\\
'''Zim:''' You dare agree with me?! Prepare to meet your horrible doom!
* ''WesternAnimation/JackieChanAdventures''
** Happens twice in an episode, after an incident causes the talismans to lose their magical powers (by transferring them into Jade's body). Both Captain Black and Daolon Wong are holding the snake talisman while attempting to show off its invisibility power to their peers ("Am I over here? Or maybe over here?"). Then they notice that they're still being watched and discover it's because they're still perfectly visible.
** There's an interesting variation in another episode where they're dealing with a vampire that is blind and can only detect people through smell. At one point Jackie is trying to hide from him by holding his breath, only for the vampire to reveal that he has absorbed enough people's life forces to gain sight. Jackie quotes this trope verbatim.
* ''WesternAnimation/LooneyTunes'': Foghorn Leghorn rubs vanishing cream (which is just skin moisturizer) onto the naïve Chickenhawk, who heads over to the doghouse and starts gloating that "you can't fight what you can't see!" to the dog. The dog pulls out a mirror. Whoops.
** Similarly, in ''Cheese It, The Cat,'' Ralph Crumden uses "invisible ink" on Norton which actually doesn't make him invisible, but Ralph makes Norton ''think'' he is. The cat can see him but is baffled by Norton's flippancy and nonchalance. Ralph decides to try it, thinking ''he's'' invisible, and subsequently gets mauled by the cat.
* In the episode of ''WesternAnimation/MonsterAllergy'' where Elena can finally [[ByTheEyesOfTheBlind see monsters]], she pretends that she can't see Magnacat in order to save Zick. Of course, Zick and Magnacat are unaware that Elena can see the latter. She knocks Magnacat and tells Zick that she can now see monsters.
* In the ''WesternAnimation/{{Rugrats}}'' episode "Mega Diaper Babies", Lil plays "Dotted-Line Girl", a parody of [[Franchise/FantasticFour The Invisible Woman]]. At one point, attempting to sneak into Angelitron's (Angelica as a giant robot bad guy) fortress, she's spotted and Lil gasps out "But how can you see me? I'm just a dotted-line!" Angelitron's response? "Any idiot can see a dotted-line."
* ''WesternAnimation/SouthPark'': After Cartman does something especially greedy, all the other children agree to ignore him, acting like he's not there. Nobody told Butters, though, so he speaks normally to Cartman. Some other misunderstandings combine to make Cartman thinks he's a ghost, and Butters is the only one that can see him.
** In another episode, the boys are roleplaying as ninjas. Cartman's power is to have any power that he wants, so he can also turn invisible -- except for his clothing. He removes his clothing and attempts to sidle across a stage in the middle of an auction, noticing after a while that the auction has entirely stopped and all eyes are on him... and his nakedness. Cartman claims it was simply a WardrobeMalfunction.
* ''WesternAnimation/SpongebobSquarepants'': One episode had [=SpongeBob=] and Patrick turn invisible and play pranks at the Krusty Krab, pretending to be ghosts. Eventually it wears off and [[OhCrap Patrick has to warn SpongeBob that Mr. Krabs can see them.]]

* The classic psychology paper ''[[http://www.apa.org/journals/features/psp7761121.pdf Unskilled and Unaware of It]]: How Difficulties in Recognizing One's Own Incompetence Lead to Inflated Self-Assessments'' cites a newspaper story about a bank robber who believed lemon juice made him invisible to security cameras.
** Naturally, ''America's Dumbest Criminals'' has the actual film footage. Amusingly the guy was taking his sweet time, including taking out a shopping cart as if it was just a normal trip to the store.
** Formally known as the Dunning-Kruger effect, after the psychologists who conducted the study.
* [[http://www.highbeam.com/doc/1G1-98595053.html Some]] [[http://www.nytimes.com/1994/05/01/nyregion/suspect-in-6-brooklyn-killings-is-arrested-in-georgia-murder.html people]] apparently believe that a magic ritual can turn them invisible, despite all evidence to the contrary.
