->''"From the night of Brad's stage dive. All of a sudden, I'm getting electromagnetic readings up the wazoo. For some reason, it's a legit haunting now."''
-->-- '''Dean Winchester''', ''Series/{{Supernatural}}''

When they're not tormenting humans or scaring pets, ghosts are interfering with technology, appearing on video screens, making radios and [[OminousTelevision TVs crackle]] and playing with the lights. Alongside [[GhostlyChill cold spots]], EM interference is one of the "recognized" signs of a haunting. One variation, known as EVP (electronic voice phenomena), specifically involves anomalous voices or other sounds on electronic audio recordings. Ghosts also appear on camcorder screens, night vision cameras, and of course, infrared cameras.

An electromagnetic ghost may be a WalkingTechbane if the interference is strong enough.

Not to be confused with VirtualGhost (which is a "ghost" projected by technological means); HauntedTechnology, (when the ghost is actually inhabiting a machine); or GhostInTheMachine (which is nothing to do with ghosts at all). This trope covers any supernatural activity that makes electrical systems malfunction as a side effect of their presence.

Compare MagicHarmsTechnology, when magical forces rather than supernatural creatures is the cause of technological interference.

!!Examples:

[[foldercontrol]]

[[folder:Advertising]]
* A commercial for Esurance implies this. A man is walking past a house at night and sees all of the lights flashing and believes that something terrible is coming. In truth, the family is out to eat and the son is playing with a light control app on his parents' smartphone.
[[/folder]]

[[folder:Films -- Live-Action]]
* ''Film/ComePlay'': Larry's presence tends to short-circuit all the lights in the area, [[spoiler:since he needs power to sustain his presence in this world]].
* ''Film/DontListen'': When the ghost [[spoiler:of the witch who was executed 300 years ago]] begins haunting, electronic devices tend to get screwy, like the child psychologist's radio flickering before [[spoiler:the ghost possesses her and kills her]]. There's also Eric hearing his by-then-dead son's voice calling for help in a recorded message he sent to his wife.
* ''Film/{{Eternal}}'': When Wildcat drives on to the ground of Elizabeth's mansion, the radio in her car suddenly cuts out.
* ''Film/TheFrighteners'': When the ghosts haunt a house, light flickers and objects move by themselves.
* ''Film/GhostFromTheMachine'' has the protagonist build a device that creates an intense electromagnetic field in order to bring ghosts closer to the land of the Living, in an attempt to resurrect his dead parents. However, it also brings back his neighbor's dead wife, and [[spoiler:the psychotic murderer/suicide who used to own his house]]...
* ''Film/GhostsOfWar'': When the Helwigs rise from their graves, all of the lights in the chateau go out.
* In ''Film/TheGravedancers'', the presence of the ghosts in the mansion causes the lights to surge and dim wildly.
* ''Film/TheInnkeepers'' has Claire and Luke using recording equipment to pick up EVP and find the ghost that they think is haunting the hotel.
* The ghost in ''Film/LemonTreePassage'' interferes with electronics; causing Sam's car radio to start blaring, switch channels, turn off, et cetera.
* In ''Film/OurHouse'', the ghosts are sometimes presaged by flickering lights and interference with the TV displays. Then again, as often as not, it's the fault of Ethan's machine, which has tremendous power requirements.
* In ''Film/Poltergeist1982'', the ghost researchers use this sort of equipment to monitor the ghostly activities in the house. After one supernatural occurrence, one of them even notes "It's electrical -- you can smell the charge."
* In the 2002 adaptation of ''Literature/TheRing'', Samara Morgan imprints images on a blank videotape (cursing it in the process) and can manipulate televisions when someone's week is up, up to and including emerging from the screen. Before her death, she had similar abilities to psychically imprint images on electromagnetic film. In fact, unlike the original Japanese version which includes weird stuff like communicating with germs, ''all'' Samara's powers seem to be magnetism-based. Tampering with videos and surveillance cameras, levitating metal objects, even causing fatal seizures are things that can be done with sufficiently precise EM waves.
* In ''Film/{{Savaged}}'', Zoe's presence at the mine causes the lights to flicker and various pieces of machinery to malfunction.
* In ''Film/ScarecrowSlayer'', the presence of the Scarecrow causes mobile phones to fill with static and stop functioning.
* In ''Film/TheSixthSense'', Malcolm discovers that the ghosts actually exist when he can hear them on a tape recorder.
* Averted in ''Film/TheStoneTape'' despite the wide array of electronic equipment used to study the ghost. Eventually, the scientists realize that what they hear and feel is the brain's reaction to whatever is [[LivingMemory imprinted into the walls]]; this is why some people are more sensitive to paranormal phenomena than others.
* ''Film/WhiteNoise2005'' is about "electromagnetic voice phenomena", where voices from beyond appear on audio and video recordings.
[[/folder]]

[[folder:Literature]]
* In ''Literature/AlternateRoutes'', ghosts can make their voices heard on radios and their faces appear in the static on an untuned analog TV set (although since the story is set after the switch to digital TV signals, the only character who ''has'' an analog TV set is a ghost peddler who keeps an old one around specifically for communicating with ghosts with).
* In Creator/TimPowers' ''Fault Lines'' trilogy (consisting of ''Literature/LastCall'', ''Literature/ExpirationDate'', and ''Literature/EarthquakeWeather''), ghosts can cause interference with compasses, call people up on phones and appear on TV talk shows (at least, on the version being watched by the person they're haunting) to gain important information.
* In ''Literature/GhostRadio'', the protagonist Joaquin runs a radio station where people can call in and describe [[GhostStory ghost stories]] on the air. [[spoiler:His dead friend Gabriel gets to him mid-broadcast through one of these calls, and messes with him in general by [[EvilPhone hijacking phone lines]], making televisions [[TheTelevisionTalksBack show him strange imagery]], and eventually causes him to visually hallucinate what Joaquin's callers are describing, all out of spite for how Joaquin survived multiple near-fatal accidents that Gabriel did not. Gabriel comments at one point that radio is a major conduit for spirits to reach the human world.]]
* In ''Literature/HellHouse'', the haunting is ''literally'' electromagnetic, as ghosts are essentially an energy field which survives the death of the body. [[spoiler:As a consequence, they can be destroyed by a good, hard degaussing unless they are protected in some fashion.]]
* ''Literature/JohnnyMaxwellTrilogy'': In ''Johnny and the Dead'', the Dead are able to manipulate, damage, or generally mess around with radios, telephones, televisions, arcade games, jukeboxes, computer networks, satellites, and radio telescopes. Justified because one of them was an electronics genius in life, while another is Albert Einstein's distant cousin.
* In ''Literature/TheNightsDawnTrilogy'', the Possessed -- human souls returning from death via DemonicPossession -- disrupt any nearby 27th century equipment. When the Possessed take over a planet, they must rely on archaic mid-20th century technology as modern equipment ceases functioning or is bugged beyond usability.
* ''Literature/RepairmanJack'': The ghost from ''The Haunted Air'' makes a clock radio's LED display run in reverse and causes a television to show programming from TheEighties twenty years later, even when it's unplugged and had its internal components removed.
[[/folder]]

[[folder:Live-Action TV]]
* Robin the caveman from ''Series/GhostsUK'' can make the lights flicker, although it hasn't been explained why. It does require conscious effort on his part, however, rather than his presence alone. His [[Series/GhostsUS US counterpart]] Thorfinn can do the same thing, explained as being due to him being killed by a lightning strike.
* Of a sort in ''Series/GhostWars'' in that the ghosts in question are warded off by electricity of any sort.
* ''Series/LaFemmeNikita'': In "Psychic Pilgrim", Nikita poses as a psychic for a terrorist who wants her to hold a seance for his dead son. She uses this trope to get him to turn off the building security system so it won't cause interference.
* ''Series/TheSarahJaneAdventures'': In "[[Recap/TheSarahJaneAdventuresS3E7E8TheEternityTrap The Eternity Trap]]", this is exploited to detect the presence of ghosts more scientifically, and prove the house really is haunted -- although (as Sarah Jane is quick to point out) [[DoingInTheWizard they aren't technically ghosts]]. (Or at least, that's how it seems until [[RealAfterAll the final moments of the episode]]...)
* In ''Series/{{Supernatural}}'', [[https://supernatural.fandom.com/wiki/Electromagnetic_Interference ghosts and other supernatural beings can cause electromagnetic interference by flickering lights and making them explode]]. When not causing interference, normally invisible ghosts show up on camcorder screens and the EMF detectors used by ghost hunters.
[[/folder]]

[[folder:Multiple Media]]
* Franchise/{{The Slender Man|Mythos}} is often shown to muck up electronic equipment, causing static, audio and visual distortion, missing frames, added frames, and general horror. A video camera is also a way to see him when he is otherwise invisible. In ''WebVideo/MarbleHornets'', trying to film him tends to make it worse.
[[/folder]]

[[folder:Music Videos]]
* The song and music video for [[https://www.youtube.com/watch?v=nJ3jl794mGs "White Noise"]] by Music/{{PVRIS}} are about a frustrated ghost that wants to communicate with the living but can't do anything other than cause interference.
-->''It's hard to be what you need through a static screen\\
Been trying to speak for weeks and weeks\\
Open my mouth, all that comes out\\
Is white noise and incomprehensible sound\\
And all you ever do is turn me down''
[[/folder]]

[[folder:Podcasts]]
* ''Podcast/TheMagnusArchives'':
** It is implied that this is why the "bizarre" statements (i.e., all the ones the audience hears) come out distorted when the archivist tries to record them on a computer, so he has to use an old tape recorder. Some of those making statements seem to have come across similar distortion.
** In the episode "Growing Dark" it is hinted that something supernatural is causing the lights to stop working in the narrator's girlfriend's flat. They replace the bulbs, check the fittings and call in an electrician but can find nothing apparently wrong. Then [[spoiler:subverted when it turns out not to be supernatural, merely bizarre -- someone (presumably his girlfriend's strange flatmate) keeps unscrewing all the bulbs just enough to break the connections]].
[[/folder]]

[[folder:Tabletop Games]]
* Exaggerated (or drawn to the logical conclusion) in ''TabletopGame/BladesInTheDark'': ''all'' ghosts are electromagnetic phenomena, by the virtue of {{ectoplasm}} (or rather "''electro''plasm") always carrying electric charge in this setting, which its residents have learned to exploit in order to launch an industrial revolution.
* ''TabletopGame/GeistTheSinEaters'' affords ghosts several Numina that allow them to do this, such as Ghost Sign (imprint a message in a medium) or Left-Handed Spanner (make technology go haywire). As such, several Sin-Eaters have necromantic Ceremonies that rely on these tropes, like Spectral Photography (take a photograph of an area, get a glimpse of the most dynamic ghost activity that happened in the last few days) and Dead Voices on Air (leave a specially-prepared camera behind, and it will capture whatever ghostly activity occurs in the meantime).
* ''TabletopGame/{{Orpheus}}'' gives characters the Shade Haunter, which allows them to create and control electronic interference as part of their abilities.
[[/folder]]

[[folder:Video Games]]
* Happens in ''VideoGame/AmberJourneysBeyond'', complete with gadgets to track what happens. Two examples center around a TV in the master bedroom. At one point, a camera in the room shows a ball of white light coming out of the TV and morphing into a key, dropping itself into a drawer. Then, if you actually use the TV, it shows a [[ImpendingDoomPOV creepy POV shot]] of someone running through the house, screaming and eventually coming up the stairs and knocking you out.
* All ghosts in the ''VideoGame/TheBlackwellSeries'', including Joey, can interfere with radio-based devices simply by getting close to them. This is crucial to solving several puzzles throughout the games. Also, Rosa notes that she had to install cable just so she could watch TV with Joey around.
* A significant part of [[ParanormalInvestigation investigations]] in ''VideoGame/ConradStevensonsParanormalPI'' is detecting the electromagnetic disturbances ghosts generate around them with an EMF meter, and strange EMF readings can be used to 'track' ghosts. Manifested entities will also sap battery power from your equipment if you try to walk through them.
* Appears in all three ''VideoGame/DarkFall'' games. In the first one, sometimes ghosts talk to you through the [[EvilPhone reception phone]], Polly and Nigel's surveillance system occasionally flickers into showing dark splotches or how various rooms appeared in the past, and distorted audio files on their computer can be edited to reveal voices. The second, ''Lights Out'', has an old World War II radio that's been rumored to be haunted, and tuning it to a certain frequency and using ghost-hunting goggles reveals an evil voice talking to you. A haunted TV appears in ''Lost Souls'', displaying cryptic images that provide clues to [[spoiler:the code for the ring mechanism]].
* While most supernaturalness in ''VideoGame/DeadSpace1'' and ''VideoGame/DeadSpace2'' is [[spoiler:inside Isaac's head]], ''something'' is interfering with RIG transmissions.
* The ghosts in the ''VideoGame/FatalFrame'' series tend to cause radios, tape players, televisions, telephones or other kind of electronics to act up.
* In response to a supernatural event in ''VideoGame/FirstEncounterAssaultRecon'', the lights go wild (most of the time they just flicker, but in some instances, they overload and shatter or just mysteriously break), your radio crackles and "unknown origin" is shown as the source of the transmission. Alma also appears on monitors occasionally, like a visual equivalent of an EVP. [[spoiler:Her contractions cause an EMP-like effect in ''F.E.A.R. 3''.]]
* Many of the powers in ''VideoGame/GhostMaster'' are electrical in nature, such as [[https://ghostmaster.fandom.com/wiki/Blow_Fuse Blow Fuse,]] [[https://ghostmaster.fandom.com/wiki/Blackout Blackout,]] [[https://ghostmaster.fandom.com/wiki/Wild_%26_Crazy Wild & Crazy,]] and [[https://ghostmaster.fandom.com/wiki/Strange_Behaviour Strange Behaviour.]] Technology is also one the '[[HauntedFetter fetters]]' or places ghosts [[HauntedTechnology can be anchored]].
* While White Face from ''VideoGame/{{Imscared}}'' is never stated whether to be a ghost or not, it does have the appearance and behavior of one, and it does interfere with technology: [[spoiler:[[TheFourthWallWillNotProtectYou your computer]]]].
* ''VideoGame/JRs'': If the ghost is possessing an animatronic, the camera they're on may begin flickering. The animatronic's stability counter in the control panel can also start glitching out.
* The ghosts of dead miners in ''VideoGame/KentuckyRouteZero'' appear as flickering images through the sparking of the electrical rail, but only if the lights are off.
* Taping [=EVPs=] and scanning for electromagnetic signs of ghosts is a crucial part of ''VideoGame/TheLostCrown: A Ghost-Hunting Adventure''.
* The "ghosts" from ''VideoGame/{{Oxenfree}}'' speak through heavily distorted radio messages, and their control over time causes {{ominous visual glitch}}es. Tuning the radio finds new broadcasts from them and forces them out of possessed characters. It's played with, as they're not ''technically'' ghosts (and they themselves mock the term) but [[spoiler:the crew of nuclear submarine that was transported to another dimension after its destruction]].
* The EMF reader in ''VideoGame/{{Phasmophobia}}'' is used to detect ghost activity. Higher levels mean a stronger presence and more activity, and only the most aggressive ghost types can trigger a level 5 reading. All types of ghost can make lights flicker and turn radios and [=TVs=] off and on, and they will always make your flashlight flicker when they're about to hunt. In addition, certain types of ghost can respond to your questions on the Spirit Box, an FM radio device that can pick up ghost speech. Raiju in particular interact very dangerously with any electronics in the area: They'll react every time, be it the lights in the room or your own equipment (which makes them easier to track), but the Raiju will react as well, moving faster and being much more eager to hunt you down.
* In ''VideoGame/SengokuBasara 3'', [[TheWoobie Oichi]] has a similar "static effect" sometimes when she speaks, in a reference to this phenomenon.
* ''Franchise/SilentHill'':
** A staple of the series is a pocket radio that, while seemingly dead, blasts out static in the presence of monsters. At certain points in certain games, it can pick up mysterious broadcasts.
** In ''VideoGame/SilentHillShatteredMemories'', you can only see ghosts by looking at them with Harry's cell phone camera, and "echo memories" -- [[LivingMemory lingering traces of emotionally charged events]] -- cause the phone to give off weird static and feedback.
* Signibble from ''VideoGame/YokaiWatch'' is a mischievous Mysterious Tribe Yokai who likes to mess with cell phone reception and change the channels on TV sets.

[[folder:Web Animation]]
* ''WebAnimation/TheCyanideAndHappinessShow'' has one scene in "Now That's What I Call Spooky" in which wrestler ghosts can only be shown infrared thermal camera screens and are invisible to night vision cameras.
* Lewis from ''WebAnimation/MysterySkullsAnimated'' has caused the group's van to shut down at least twice and unknowingly shocked Arthur through his metal prosthetic arm when Arthur tired some desperate percussive maintenance. Not that Lewis would mind electrocuting Arthur since his goal since coming back seems to be murdering him.

[[folder:Webcomics]]
* The eponymous, half-ghost main character of ''Webcomic/{{Erma}}'' and her mother both do [[https://tapas.io/episode/261879 this]].
* ''Webcomic/{{Hejibits}}'' has [[http://www.hejibits.com/comics/spectral-signal/ this]] example.
* One ''Webcomic/LoadingArtist'' strip is about [[https://loadingartist.com/comic/going-going-ghost/ a ghost talking about how he was friends with an Egyptian ghost, but unfortunately, it wasn't long before his presence causes the television set to start flickering and sprouting out static]].

[[folder:Web Videos]]
* Jay Are's backpack in ''WebVideo/TheAdventuresOfTheLeagueOfSTEAM'' is supposedly a device for picking up [=EVP=]s.
[[/folder]]

[[folder:Western Animation]]
* The ''WesternAnimation/AdventureTime'' episode "[[Recap/AdventureTimeS4E11BeyondThisEarthlyRealm Beyond This Earthly Realm]]" has Finn [[TrappedOnTheAstralPlane getting stuck in the]] SpiritWorld, where it seems he can't interact with anything in the physical plane and no one can even see him but Ice King, who has "wizard eyes", then gets stuck there itself. It turns out they ''can'' effect things subtly, which Finn discovers when he moves around near a television and sees the static start to change.
* In ''WesternAnimation/HazbinHotel'' Alastor the Radio Demon, probably as part of his EvilLuddite shtick, cannot be filmed. In his first attempt at making a television commercial he is explicitly off-screen by being behind the camera. When Vaggie starts filming him in annoyance at his mocking, the video glitches horrifically to the point the ''camera dies''. Alastor warns her off that "this face was made for radio" but does agree to help with the second commercial if she never makes him do anything video-related again. He accidentally doesn't stand far enough off-screen in that commercial, and from the short bit we see is ''still'' glitching like mad, so it may even be involuntary.
* In the ''WesternAnimation/SpongeBobSquarePants'' episode "[[Recap/SpongeBobSquarePantsS2E16GraveyardShiftKrustyLove Graveyard Shift]]", Squidward tells [=SpongeBob=] the story of the Hash Slinging Slasher to scare him. He tells him that there are three signs heralding the arrival of the Slasher, and the first one is the lights turning on and off. Later, the lights at the Krusty Krab do start turning on and off, which Squidward at first dismisses as cheap wiring, but then the other two signs occur, and a mysterious figure approaches the door. Fortunately, it's just the night fry cook Krabs had just hired, but that didn't explain the lights. Then they see the real culprit: Film/{{Nosferatu}}.
