->''I, I must remind you that the, uh, scanning experience is usually a painful one, sometimes resulting in nosebleeds, earaches, stomach cramps, nausea.''
-->-- [[YourHeadASplode A very unfortunate man]], ''Film/{{Scanners}}''

Purely mental battles are hard to show with special effects. Sure, you can have the characters sweat, strain, or show [[CrossPoppingVeins veins swelling on their forehead]]. But when a character with {{Telepathy}} or other PsychicPowers [[DeadlyUpgrade pushes them to the limit]], or when a character is under [[MindProbe mental]] [[MindRape attack]], nothing quite exemplifies the true state of affairs like a thin trickle of blood oozing from their nose.

Exactly how much damage this implies varies from place to place. Exaggerated versions of this include blood from the eyes, or eyes and nose simultaneously. Within nodding distance of TruthInTelevision, as rupture of the capillaries inside the nasal membranes ''is'' a recognized (albeit rare, and usually only seen in people already in poor health) symptom of dangerously high blood pressure, such as that caused by extreme emotional stress, physical strain, or -- presumably -- intense psychic effort. Sudden nosebleeds under stress have been known to precede strokes.

An early example of the trope was the film adaptation of Creator/StephenKing's ''Literature/{{Firestarter}}'', where it was used in place of the original book's far-less-visible "tiny cerebral hemorrhages". However the [[http://politedissent.com/archives/1581 first]] actual depiction can be found in the film ''Film/{{Scanners}}'' (pictured above), which came out a few years prior.

Bleeding from the eyes or ears instead of or alongside a nosebleed could be considered variations of this trope. Blood from the ears in particular is a more worrying sight than a nosebleed, because it's a highly recognisable sign of head trauma.

Polite Dissent, a comics blog written by a physician, regularly provides examples of [[http://www.politedissent.com/index.php?s=nosebleed&submit=search Psychic Nosebleed Zen]], which the author has dubbed "[[http://www.politedissent.com/archives/868 epistaxis telepathica]]".

Sometimes overlaps with DeadlyNosebleed if the psychic battle is also doing real, physical damage to the character. Only occasionally related to BloodFromTheMouth.

For nasal hemorrhages that are more of [[{{Fanservice}} sexual]] than [[PsychicPowers psychic]] nature, see {{Nosebleed}}. And for a psychic trope that may result in such, see DirtyMindReading.

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* In ''Manga/{{Akira}}'', the new, weaker psychics developed and employed by the BigBad Tetsuo tend to have this. Tetsuo, and the other more powerful psychics, won't get any such ill effects.
* Manga example, In ''{{Gantz}}'', the psychics Sakata and Sakurai get a slight nosebleed when they use their psychic abilities. [[spoiler: This is explained as using these abilities pushes their bodies past limits that just shouldn't be pushed, resulted in wearing out their insides in a process that's exactly like aging: although they always appear to be the same age, their bodies are becoming that of old men by using these abilities. Of course, considering the Old Man character that's the Hero's Right Hand Man, this might not be a BAD thing, per se.]]
** Oh, but it gets better. Later on, when [[spoiler: Sakata holds back an enormous alien at the risk of his life to give Sakurai and Reita a chance to escape]], he bleeds from the nose, mouth, eyes ''and'' ears. Ouch.
* In ''LightNovel/FullMetalPanic'', Tessa has a massive nosebleed [[spoiler:after melding her mind with Kaname's and helping her assume direct control over the Tuatha de Danann]].
* In ''Manga/{{Naruto}}'', after using his Amaterasu Sharingan technique, one of Itachi's eyes begins to bleed profusely and becomes extremely bloodshot. [[spoiler:After using Amaterasu and several other similar techniques repeatedly, Sasuke's eye bleed ''even more'' and are so bloodshot they look like they're about to '''explode'''.]]
** [[spoiler: While trying to trap the 9 tailed fox inside his Chibaku Tensei meteor, Pain gets a nosebleed from the strain of the technique.]]
** When Inoichi telepathically communicates to [[spoiler:an entire army of 20,000 at once]] he ends up getting a nosebleed.
* In ''[[{{X1999}} X/1999]]'' Subaru Sumeragi has blood coming from his ears after [[JourneyToTheCenterOfTheMind going within Kamui]] to bring him back from his borderline AngstComa after [[spoiler: Fuuma's FaceHeelTurn and Kotori's murder]].
* A common occurrence in ''{{Psyren}}''. Psychicers commonly have nosebleeds after they either develop or exhaust their abilities.
* In ''WeissKreuz Gluhen'', Shimojima develops a nasty nosebleed while Berger is using his PsychicPowers to force Shimojima to drive his car out of control. The nosebleed abates when Berger stops.
* In ''MahouSenseiNegima'' when Haruna's artifact is used to defend from a massive attack on all sides, she is knocked unconcscious and recieves a slight head injury from the feedback received from her artifact.
* In ''[[Anime/AfterWarGundamX Gundam X]]'', ex-Newtype Jamil Neet starts bleeding from the ears while attempting to communicate with another Newtype, Tiffa Adil.
* Anemone from ''EurekaSeven'' has these, but it's used as an indicator of the abuse her job puts on her mind and body rather than actual psychic powers.
* While not due to psychic efforts, near the end of ''SummerWars'', Kenji's nose starts to bleed at the immense effort of mentally decrypting a two-thousand digit key, entirely in his head, with only a few seconds left until the satellite drops.
* In ''SenkouNoNightRaid'', Yukina suffers one after [[spoiler: working with Shizune and her seer powers to show a strong illusion of an atomic bomb in effect to a crowd of people as a warning.]]
* In ''Manga/YamadaKunAndTheSevenWitches'', this has happened a couple of times when Meiko Otsuka and others with her telepathy power overexert themselves.
[[/folder]]

[[folder:Comic Books]]
* Max Lord, of the ''JusticeLeagueOfAmerica'', had a small nosebleed whenever he used his metahuman "push" ability. In ''Justice League: Generation Lost'', Max [[spoiler:pushed his powers far enough to erase memories of his existence from ''everyone'' on the planet except for ComicBook/BoosterGold, Fire, Ice and ComicBook/CaptainAtom]]. To do so, he had to constantly replenish his blood supply from the massive haemmorhage it gave him.
* The ''Comicbook/FantasticFour'' series has quite a few examples cropping up from time to time. Any character that suffers psychic stress seems prone to the Psychic Nosebleed. In recent times it happened in both the movie and the ComicBook/CivilWar. For example we have Sue Storm, the Invisible Woman. Also, Marvel Boy/Justice also got nosebleeds when overusing his psychic powers.
* ''Comicbook/XMen''.
** Jean Grey and Rachel Summers. Hardly surprising, since the second is the first's time-travelling daughter from an alternate future.
** Comicbook/{{Cable}} (Jean's Clone's time-traveling son from ''this'' reality) subverted this on one occasion by bringing him''self'' back from the dead without any problems. Usually, though, he suffers psychic nosebleeds when doing things like inadvertently mind-controlling a continent's worth of people, saving airborne continents from crashing after gravity comes back into effect, or beating up the cosmically-powered Silver Surfer in an attempt to [[ExplosiveOverclocking burn out his own powers]].
** In the Marvel Age we have ComicBook/EmmaFrost. She constantly gets severe nosebleeds as her abilities are awakening.
** In the 80s graphic novel ''ComicBook/GodLovesManKills'', a brainwashed Professor X psychically attacked Storm and Cyclops, almost killing them--they were left unconscious, with [[DeadlyNosebleed blood trickling out their noses]].
* The villain Saturn Queen from the ''ComicBook/{{Supergirl}}'' comics.
* Sophie, one of the Stepford Cuckoos from ''New X-Men'', suffered a psychic nosebleed before her death while using Cerebra (the upgraded version of Cerebro). This was a combination of several factors; she wasn't a strong enough psychic to control Cerebra, and was on the [[DeadlyUpgrade mutant-power-boosting drug]] "Kick" in order to do so. Combined with her inexperience with the machine, it's somewhat unsurprising that it led to her death.
* In an issue of Creator/ChuckDixon's ''ComicBook/TeamSeven'', a Russian telepath tries to use her PsychicRadar to track them through the Cambodian jungle. It doesn't work, due to a ''"greater power."'' She gets a Psychic Nosebleed for her trouble.
[[/folder]]

[[folder:Film]]
* This happens to Zorg in ''Film/TheFifthElement'' when having a telephone conversation with the BiggerBad.
* The movie ''Film/TheButterflyEffect'' has the main character start to get nosebleeds after he has several blackouts. Each blackout (i.e. each use of his power) cause worse and worse damage to the main character's brain. This is caused by the main character's RippleEffectProofMemory kicking in and the memories being physically written into his brain and co-existing with the older sets. After the first couple of times the main character fiddles with the past, he gets an MRI and the doctor notes that his brain has all the age-induced scarring of someone twice as old as him.
* The 80s movie version of ''Film/{{Dune}}'' involved a scene in which several Bene Gesserit (psychic witches) cried blood when Paul drank [[PsychoSerum the Water of Life]].
* ''Film/{{Scanners}}'' not only [[TropeMakers invented this trope]], it pushed it farther than anyone has since, where it shows that enough psychic energy not only causes noses to bleed, but veins to pop leaks, eyes to bulge and even pop out, and, in one famous scene, ''[[YourHeadASplode an entire head to explode]]''. There's also a scene where the psychic protagonist is explicitly trained to [[BodyHorror mess with the opponent's biological functions]]. After all, it's hard to stay focused if you're having a heart attack or worse.
* In ''Film/TheRing'', characters experience a nosebleed whenever the Curse's influence grows particularly strong.
* Shown to happen to the three guys from ''Film/{{Chronicle}}'' whenever they overuse their powers.
** [[spoiler:Also seems to work like a psychic connection between the three when something happens to one of the others.]]
* In the 2005 ''Film/FantasticFour'', Susan Storm aka Invisible Woman, suffered a nosebleed when she formed a force field around the ensuing "supernova" her brother Johnny Storm aka The Human Torch created to defeat Dr. Doom. It also happened on the Brooklyn Bridge, when she first discovered her force field abilities by containing another (unrelated) fire. In the DVD cast commentary, Jessica Alba mentioned that she liked the idea, since it shows how much she's pushing herself.
* ''Film/ResidentEvilApocalypse'' had this at the end. Security guard nosebleeds and dies.
* In ''Film/LetTheRightOneIn'', something similar to this happens when [[spoiler: vampires enter without being invited. Well, more like they start bleeding from... everywhere.]]
* In ''Film/{{Firestarter}}'', Andy has this happen to him whenever he uses his [[JediMindTrick mental domination]] powers.
* Used in ''TheWizardOfGore'' to show that Montag had the morgue attendant hypnotized. It's later revealed that the attendant died from the experience.
* Used in ''Film/{{Valentine}}''; whatever was killing the victims left all of them with nosebleeds after they died.
* Not a nosebleed, but the same principle applies in ''WesternAnimation/TheIncredibles''. When Violet's force field gets overloaded (for example, by a several-ton killer robot), she get's knocked unconscious, and takes her several minutes to get back into the battle.
* ''Film/PacificRim'': Using the mental link without a partner or [[spoiler: on a {{Kaiju}} brain]] causes aneurysms, shown as this.
* Inverted in the Chevy Chase comedy "Modern Problems", where he uses his new psychic powers to make someone else's nose bleed.
* The DarkMessiah in ''Film/ChildrenOfTheCornIITheFinalSacrifice'' causes a man to bleed from his nose by carving a wooden effigy with a knife. It gets so bad that his entire face starts bleeding, and he dies.
[[/folder]]

[[folder:Literature]]
* Despite the frequent use of PsychicPowers in ''Literature/{{Fingerprints}}'', only one psychic nosebleed ever occurs: when a character attempts to use their power on a group of guards who are psychic-blocked. All of the psychics suffer other varying side-effects from overuse of their powers, though.
* In Creator/SimonRGreen's ''Literature/{{Deathstalker}}'' series, Espers and the Maze People have this happen rather often, when pulling off big time abilities.
* In the Franchise/StarWarsExpandedUniverse novel ''Literature/DeathStar'', a marginally Force-Sensitive stormtrooper called Nova Stihl is hit hard by the [[EarthShatteringKaboom destruction of the prison planet Despayre]], the Death Star's first test. Nova woke up screaming and felt like he had heard a million people cry out, all at once, as they were killed. Shortly afterwards the Death Star destroys Alderaan. For that, Nova was awake, but he was knocked unconscious and woke up with a nosebleed and intense muscle tremors. Poor conflicted bastard.
* In the ''Literature/KingmakerKingbreaker'' books, those forced to perform the Weather Working suffer from this.
* In ''Literature/KingOfTheWaterRoads'' this is often the first price exacted for spells. It starts with the thin trickle, but the more magic is used, it can expand to a steady pour, then to coughing blood along with the nosebleeds.
* Happens to [[{{Nightside}} John Taylor]] when he pushes his gift too hard, either by using it too many times in quick succession or by forcing his perceptions past some kind of mystical/psychic barrier.
* In a subversion of the trope, in ''Literature/TheMerchantPrincesSeries'' by Creator/CharlesStross the ''Psychic Nosebleed'' is a common side effect of the dimension hopping powers of said princes. The subversion comes from the fact that it is a side effect of malignant hypertension and can be treated with beta blockers and other medication.
* In Literature/{{Abarat}}: Days of Magic, Nights of War Malingo suffers from this when Carion is interfereing with his control over the glyph.
* An odd case occurs in DarknessVisible: Though venturing is not a purely psychic talent, there is a lot of mental strain involved, particularly the way that Lewis does it. When he pushes himself too far, the first outward sign is a nosebleed.
* Happens in ''Literature/TheShadowSpeaker'' when Ejii tries to search Dikeogu's mind.
* Christine Feehan's GhostWalkers series has this happen as well as cerebral hemorrhages. But it's also said that the high numbers of hemorrhages and strokes in Shadow Game are anomalous.
* In ''PerdidoStreetStation'', the activation of [[spoiler: Isaac's moth-baiting apparatus]] sends out such a powerful psychic blast across New Crobuzon that sensitives all over the city develop nosebleeds, two of them ''[[DeadlyNosebleed fatal]]''.
* In ''Literature/RachelGriffin'', one character is found "gushing" blood from intense mental stress caused by fighting against a magical compulsion. Overlaps with DeadlyNosebleed, as she passes out from bloodloss and explicitly would have died without prompt treatment.
[[/folder]]

[[folder:Religion]]
* In ''Literature/TheBible'', Jesus is praying at the Mount of Olives just before His arrest, and His sweat appears like drops of blood (Luke 22:44). As mentioned in the Real Life section below, this is likely due to the stress brought on by His knowledge of what's about to go down.
[[/folder]]

[[folder:Live Action TV]]
* In ''{{Smallville}}'', when Chloe telepathically connects with the [[MacGuffin crystal of knowledge]] [[spoiler:using her Brainiac abilities]] to save Clark, she gets a nosebleed before collapsing.
* ''Series/{{Heroes}}''
** Telepathic cop Matt Parkman in the first season
** Angela Petrelli in the second season, when she (unsuccessfully) resisted Matt's mental assault.
** Peter Petrelli in the second season finale.
** Hiro Nakamura, plus a psychic ear bleed, a burst vein in his eye, and fainting. And now [[spoiler:a brain tumor]]!
** Some other characters as well, such as The Haitian and Eric Doyle. For a list of all the examples, see [[http://heroeswiki.com/Nosebleed here]].
* Just about everyone who had been TouchedByVorlons in the miniseries ''Series/{{Taken}}'' did this. In fact the series ended with the super psychic girl giving all her fellow abductees nosebleeds to push out the small transistors that the aliens had placed in their brains, to prevent future re-abductions.
* ''Series/BabylonFive'', the obvious source of TouchedByVorlons, has Lyta Alexander, who winds up with bleeding eyes. Bleeding, black-socketed, empty eyes.
** A variant: when Lyta forces Bester out of her mind in the fourth season, he reacts as if punched in the jaw.
*** In another confrontation Bester hypothesises that Lyta can't take his entire team at once since she is sweating after pushing back two. She replies that if she pushes too hard she might pop someone's blood vessel and cause them brain damage. Posturing ensues.
* Similarly, various psychic characters in ''Series/TheFortyFourHundred'' have had nosebleeds when using their powers.
* And of course, we can't forget the ever-lovin' trope-hoggin' ''Series/StarTrekVoyager'', where Kes had been known to give the crew {{Psychic Nosebleed}}s (usually under MindControl).
* Sci-fi show ''Series/{{Threshold}}'' has Creator/CarlaGugino's character getting nosebleeds every time she even remotely hears the alien signal - EVEN when she's talking on a phone to a friend on a quiet private plane, and neither the friend nor the audience can hear the signal being played on the plane.
* In the fifth season of ''Series/BuffyTheVampireSlayer'', Willow gets some of these after using a teleportation spell on Glory.
* In ''Series/StarTrekDeepSpaceNine'', when Kira allows one of the Prophets to take her body to fight a Pah Wraith (in the body of Jake Sisko), the exertion gives her a Psychic Nosebleed.
** In the episode "The Muse", Jake experiences a Psychic Nosebleed ([[spoiler:twice]]) because an alien creature is [[spoiler: stimulating his creativity in order to feed off his mental energy]].
* In ''Series/{{Lost}}'', this occurs whenever a consciousness becomes "unstuck in time" and is forcibly moved between the past and the future without a constant. Those suffering the effects of temporal displacement experience headaches, confusion, memory loss, nosebleeds, and eventually death by cerebral hemorrhage. A major character has died because of this.
** Other examples abound on the show when characters willingly or unwittingly screw with the forces literally surrounding the island.
* ''KyleXY'' did this when he overused his powers. Happened more often to Jessie than it did to Kyle.
* When D'Anna uses the machine on the Algae Planet in the third season of the reimagined ''Series/{{Battlestar Galactica|Reimagined}}'', she experiences a psychic vision while her body has a nosebleed and then dies.
* Parodied in an episode of ''[[LateNight Late Night With Conan O'Brien]]'', where a psychic guest loses copious amounts of blood while using telepathy. The psychic's spoon is indeed ''nudged'', although he is now wearing a wet red shirt for it.
* Happens to Sam on ''Series/{{Supernatural}}'' when he uses his PsychicPowers to exorcise demons, first when he was learning how and later when he gets rid of an especially tough demon.
* In the season premiere of ''Series/{{Scrubs}}'' season 8, Dr. Cox gets one of these while trying to resist an infectious smile. It's more a battle of wills than psychic, but still qualifies.
** Although it takes place in one of JD's ((Imagine Spot))s.
* ''Series/{{Carnivale}}'': Ben Hawkins got one after he used some form of astral projection.
* It was [[ScrewedByTheNetwork never made clear]] whether the nosebleed was due to PsychicPowers or something else, but the "Two by two, hands of blue" assassins in ''{{Firefly}}'' had a device which caused a progression of symptoms like this: your nose bleeds a little, your nose bleeds a lot, your mouth bleeds, [[TearsOfBlood your]] [[EyeScream eyes bleed]], you die.
** More like "Your nose bleeds a little, your nose bleeds a lot, every orifice you have and a few that aren't considered orifices, like your nailbeds, bleed, you die. Screaming."
* In ''Series/StargateSG1'' Jonas Quinn gets a few of these while using precognitive abilities gained by the Goa'uld Nirrti experimenting with his DNA.
* In ''Series/{{Dollhouse}}'' a device called the Disrupter gives this and a headache to anyone with the brain structure of a Doll. [[spoiler: which comes in handy for TheReveal of Senator Perrin's origin.]]
* Subverted in ''Series/{{Cleopatra 2525}}'' when a telepath spends six months deliberately inducing a nosebleed as part of her escape plan.
* Anna of the rebooted ''[[Series/{{V 2009}} V]]'' gets psychic eyebleeds when she uses her bliss on a human.
* On ''Series/{{Fringe}}'', if [[spoiler: an Observer]] "reads" you, you can fight it. Symptoms include nosebleeds, bloody eyes, permanent brain damage, and death. (But you might keep him from reading you.)
* In an episode of ''Series/{{Leverage}}'', master manipulator Nate triggers a psychosomatic illness in their target of the week, causing Parker to marvel, "Did you just give a guy a nosebleed with the power of your ''mind''?"
[[/folder]]

[[folder:Tabletop RPG]]
* In ''TabletopGame/{{Warhammer 40000}}'' nosebleeds are a 'secondary indicative symptom of proximal psychic activity'.
** Much of the fiction features serious psychic nosebleeds, taken to typical [=WH40K=] extremes. Dan Abnett's {{Ravenor}} trilogy, for example, has the loser of a high-level psyker duel [[LudicrousGibs get turned inside out]], a [[BlackSpeech language]] that causes [[BodyHorror considerable bodily harm]] and the speaker's mouth to shred, and a [[AntiMagic Blank]] whose nose bleeds continuously when a psyker keeps trying to get in his head.
** ''Cadian Blood'' has the Sanctioned Psyker Seth who is hit especially hard by this sort of thing; one devastating attack he was said to have launched and melted an enemy tank to slag, but shattered his teeth and left him in a coma for a week. When in a trance, he is only peripherally aware that his body is convulsing, bleeding, vomiting... This sort of thing is common for nearly all human psykers, save those of the Astartes and most of the Inquisition.
** As revealed in ''Betrayer'', psychics and the Butcher's Nails did not get along well in the pre-Heresy World Eaters. Angron's proximity caused psykers to start spontaneously bleeding from the mouth, eyes, and nose, while members of the legion implanted with the Nails (Angron included) found the presence of psykers triggered excruciating migraines. Those members of the Librarium unfortunate enough to be implanted with the Nails themselves frequently suffered violent deaths, either from [[PowerIncontinence losing control of their powers]], or simply getting turned inside out by raw psychic feedback.
* Very popular trope with spellcasting characters in the Fantasy meets CyberPunk [[TabletopGame roleplaying game]] ''TabletopGame/{{Shadowrun}}'', especially common with hermetic mages. Or, more precisely, not ''popular'' at all with {{player character}}s as such, but rather with their ''players''. Considering that the use of one's magical abilities, psychic battles with spirits or astral combat between astral bodies can result in fatigue and even physical injuries, a magically active character can easily overexert himself into unconsciousness or death.
* ''TabletopGame/HunterTheVigil'' has the Vanguard Serial Crimes Unit, a task force of the FBI devoted to hunting down [[SlasherMovie supernaturally-empowered serial killers]] and trained in the psychic arts. Each use of their powers requires them to take a small amount of damage, likely manifesting as a Psychic Nosebleed.
* Psionics in most versions of ''TabletopGame/DungeonsAndDragons'' has the possibility of nosebleeds ([[NightmareFuel and much, much worse]]) when psionic attacks are attempted with low wis or against psionically strong opponents.
[[/folder]]

[[folder:Video Games]]
* In the demo for ''VideoGame/BioShockInfinite'', your partner character Elizabeth can actually get a nosebleed from using too much of her psychokinetic powers as seen [[http://bioshock.wikia.com/wiki/File:20100918_ch311.jpg here.]] In the final game, Booker experiences nosebleeds as a result of traveling through rifts in space/time.
* Not quite a nosebleed, but in ''Franchise/MassEffect'', [[MindOverMatter biotics]] with lower-grade implants can suffer things like mental disorders and frequent headaches. Doctor Chakwas says that Kaidan's early-model implant port means he regularly has to deal with blinding migraines. Kaidan himself alludes to the potential for literal nosebleeds when biotics overexert themselves.
** Played straight in the ''Leviathan'' {{DLC}} for ''VideoGame/MassEffect3''. [[spoiler: During Shepard's [[JourneyToTheCentreOfTheMind conversation]] with Leviathan, we see their nose begin to bleed, due to the strain of resisting Leviathan's attempts to control them.]]
* Taken ''one [[{{Squick}} squicky]] step higher'' in ''VideoGame/MetalGearSolid3''. The Sorrow's ''[[EyeScream eye]]'' bleeds when he uses his psychic powers to "test" Naked Snake.

[[folder:Webcomics]]
* [[DeadpanSnarker Colin]] from ''Webcomic/TwoKeys'' gets a major one of these with blood coming out of his nose, mouth and ears after having a TroubledBackstoryFlashback brought on by Landon's psychic MindScrew. It left him in trouble [[http://www.mangamagazine.net/read-manga/Two-Keys-Chapter-9-Sandbagging/9/8/8?lang=en in the middle of a fight.]]
* ''Webcomic/DominicDeegan'' is prone to Psychic Nosebleed when he's been fighting titanic battles on the mental plane. See example [[http://dominic-deegan.com/view.php?date=2007-10-08 here]].
** This could also be explained that Dominic Deegan merely slammed his face onto the desk while battling in the mental plane.
** It also happens [[http://www.dominic-deegan.com/view.php?date=2004-05-06 here]].
* In ''Webcomic/ErrantStory'', garden-variety telepathic communication may or may not cause a nosebleed -- hard to tell from what we've seen of it -- but [[spoiler:possession by a [[http://www.errantstory.com/2010-05-19/4810 ghod]]]], and the communication that ensues, definitely will do the trick.
* Immense concentrations of evil can cause paladins to suffer from these in ''Webcomic/{{Goblins}}'', along with near-crippling headaches.
* ''Webcomic/PennyArcade'' has this happen to Tycho when Gabe tries to [[http://www.penny-arcade.com/comic/2007/04/09/ hate him to death.]]
* In ''Webcomic/{{Homestuck}}'', noses aren't normally drawn, but Sollux starts bleeding profusely from his eyes and mouth [[spoiler: from the immense exertion necessary to push a meteor quite a long distance away to the Green Sun that had recently been created.]] The stress is so bad that some of the veins beneath his skin burst as well.
* In ''Webcomic/{{Sinfest}}'', [[http://www.sinfest.net/archive_page.php?comicID=2850 Slick's last work produces ear bleeding.]]
[[/folder]]

[[folder:Web Original]]
* This happens to all [[PsychicPowers mentalists]] in the ''GlobalGuardiansPBEMUniverse'' when they overstress their powers past their normal limits.
* ''ThereWillBeBrawl'': [[spoiler:Luigi and Ganondorf both suffer these--and more--at the hands of Lucas and Ness, the Butchers.]]
** [[spoiler: Luigi]] gets away with ''only'' the nosebleed. [[spoiler: Ganondorf]] ends up bleeding ''from his eyes, ears, and mouth'' too.
* ''WebVideo/DragonBallZAbridged'' gives us this:
--> '''Krillin''': My turn my turn MY TURN!!!\\
'''Nappa''': ''[stops]''\\
'''Vegeta''': Wh--... Nappa, what are you doing?\\
'''Nappa''': It's his turn, Vegeta. I have to wait for him.\\
'''Vegeta''': Uhh... uh... uhh!" (nose starts to bleed).\\
'''Nappa''': You OK, Vegeta?\\
'''Vegeta''': Yes, just... just an aneurysm out of sheer stupidity.\\
'''Nappa''': "Wow! Didn't think you were that stupid, Vegeta."\\
'''Vegeta''': "WAAAARGHHHHHH!!!"
* ''Dangerous Lunatics'' has this happen when Tyler [[spoiler: gets electrocuted to the point of coma by Dr. Beatrix and Thurston, at the same time as he tries to use his power to leap out of his body]]. [[spoiler: He partially succeeds, though.]]
* ''SFDebris'' points out in his review of the Series/StarTrekVoyager episode, "Warlord," that massive mental powers often result in a nosebleed from either those using them or their victim. Most of the people on the receiving end of a possessed Kes' telepathic attack are RubberForeheadAliens with six nostrils going up their forehead, so they have ''even more'' noses to bleed from. Yuck.
* The AntiClicheAndMarySueEliminationSociety's Stephen gets one of these when his psychic powers get activated in {{Psyren}}.
* In ''Literature/PayMeBug'', this is one of the dangers of having your mind read by a [[{{Telepathy}} S]][[KnightTemplar w]][[ChurchMilitant o]][[AsskickingEqualsAuthority r]][[WithGreatPowerComesGreatInsanity d]]
* ''WebVideo/TransolarGalactica'' plays with this trope in episode VIII: Ominous, when the ship's psychic Samson attempts telepathy with the StringyHairedGhostGirl that they've taken aboard. It ends up with his [[UpToEleven head exploding]].
* In ''Literature/{{Worm}}'', overusing [[AwesomenessByAnalysis her ability]] gives Tattletale migraines.
* ''Podcast/MetamorCity'' states that casting spells or using psychic powers causes blood to rush to the head, and the increased blood pressure can cause nasal membranes to burst.

[[folder:Western Animation]]
* Happens to Jenkins in the ''WesternAnimation/StarshipTroopersInvasion'' cartoon, hours after he's overexerted himself by making a brain bug [[YourHeadASplode ''explode'']]. It's used while he's alone to illustrate that he did more to himself than he let on to his squadmates.
* Happens to Homer from ''WesternAnimation/TheSimpsons''. While undergoing lucid dream therapy, Bart and Lisa (or, rather, Homer's representation of their memory) start attacking the scenery to jar the blocked memory. Back outside, Homer receives a nosebleed.
* Dr. Killinger in ''WesternAnimation/TheVentureBrothers'' manages to induce this upon Dr. Orpheus by merely casually resisting his psychic assault until Orpheus overexerts himself.
-->'''Dr. Killinger:''' Your powers vill not vurk on me, you silly-billy.
* While not bloody, Niko in ''[[WesternAnimation/AdventuresOfTheGalaxyRangers Galaxy Rangers]]'' has, on several occasions, exerted herself to the point of collapse. The first example was "New Frontier." While attempting to detect Eliza's location, the Queen intrudes into the vision and rather violently pushes back.
* Manchester Black suffers one at one point in WesternAnimation/SupermanVsTheElite.
