{{cquote|In addition to still- and video cameras, amateur "ghostologists" use various other glitch-prone equipment — such as electromagnetic field (EMF) meters — to supposedly detect the energy from ghosts. They breathlessly report "high readings" and "significant spikes" on EMF devices and other equipment. Alas, these ghost buffs are invariably ''non-scientists'', who know little about their devices and what they're ''really'' recording, and they do not use scientific protocols and controls. They seem to think that if you use high-tech equipment, they're performing science — but they're ''actually'' engaging in [[pseudoscience]]. None of the varied instruments they use are designed for ghost detection. There ''is'' no scientific evidence that ghosts exist — let alone that they emit electromagnetic radiation or have other detectable properties.|||[[Joe Nickell]], ''Adventures In Paranormal Investigation''<ref>''Adventures In Paranormal Investigation'', Chapter 3 (12:00), audiobook version.</ref>}}
'''Ghosts''' are generally defined as "The [[spirit]] of a [[Death|dead]] person, especially one believed to appear in bodily likeness to living persons or to haunt former habitats."<ref>[http://www.thefreedictionary.com/ghost Free Dictionary's definition]</ref> There are two problems with this definition:

==Types of hauntings==
[[Image:Aliens or ghosts.jpg|thumb|right|200px|A photograph of some "ghosts"<br/>]]
It is significant that just as "UFOs" changed appearance with cultural changes (Bible stories, mystery airships, Close Encounters of the Third Kind, etc.), ghosts have varied in appearance over time. In the days when bodies were often buried in shrouds, ghosts were reported to be solid, sentient creatures, often dressed in their shrouds, who would meet those who knew them when alive and interact with them.

With the advent of photography in the 19th century, ghost photos were faked using double exposures. This created the cultural expectation of the transparent apparition, often combined with the earlier shrouded figure to create the "classic ghost". More recently, with the advent of the ubiquitous camera phone, photos taken inside dimly-lit buildings or at night will produce "orbs" where the camera flash bounces off dust or insects that pass inside the focal length of the camera and appear blurred and circular. These are claimed to be "spirits" by those too gullible or dim to understand optics.

Finally, any glance at "Genuine ghost photos" online will show that Japanese horror movie makeup is now well-known to the unquiet dead, who have adopted that look by sporting black lips, staring eyes, pointy teeth, and long, lank black hair no matter what they looked like when alive.

Ghostbusters claim there are two main kinds of ghostly hauntings: residual and intelligent.<ref>{{wayback|http://www.signsofghosts.com/ghostfacts/}}</ref> A residual spook is unaware that it's dead and will pass through a room or wash ghostly dishes without interacting with any living people in the vicinity. An intelligent ghost is the one that makes it into the movies because they're the ones that know they are dead and are pissed off about it. This results in 
them chasing {{wpl|Pac-Man}} around a maze
 [[poltergeist]] activity, strange houses in Amityville, and Freddy Krueger. Or, in a recent notorious Australian case, pushing some biscuits onto the floor.

In either case, almost all ghostly apparitions are "seen" wearing clothing, which may suggest that your clothes have a [[soul]] and that they will die when you do.<ref>Even {{wpl|Lyall Watson}} in the woo-tastic ''Supernature'' is forced to concede: [https://books.google.co.uk/books?id=vsURFLYBNEUC&pg=PT300&lpg=PT300&dq=astral+shoes+and+shirts+and+hats&source=bl&ots=axTimq22Mp&sig=29EGUOPGQVPTrxLAu8BknB9yf9Q&hl=en&sa=X&ved=0ahUKEwiwgsXgw_rUAhVpLMAKHWiZBJcQ6AEISzAG#v=onepage&q=astral%20shoes%20and%20shirts%20and%20hats&f=false "While I am prepared in principle to concede the possible existence of an astral body, I cannot bring myself to believe in astral shoes and shirts and hats."]</ref>
Ghosts cannot decide whether to haunt the exact location of their death, the site of their burial, or even just somewhere loosely associated with their life. Thus the Australian gangster Mark "Chopper" Read is said to haunt Pentridge Prison, where he served earlier in his life, rather than where he died or is buried. Ghost Tour guides, usually scientifically rigorous in their research, claim that the ghost of the last man hanged at Boggo Road gaol in Brisbane, Australia, haunts the remaining building, screaming and shrieking. However, the cell block where he was hanged was demolished years ago, and he wasn't known for loud screams while alive.

Of course, this free choice for ghosts to haunt pretty much anywhere, not just where they died or were buried, prevents hospitals and graveyards from becoming over-run with shrieking apparitions walking through walls, moving furniture, tapping people on the shoulder, or making the air turn slightly colder. Such places would become unusable, and we can be thankful that this has not happened. It is entirely coincidental that many ghostly manifestations reproduce the perceptual phenomena associated with decreased [[consciousness]]. These include "things seen out of the corner of the eye", sudden random spoken words or sounds, the sense of being watched, paralysis, the sensation of a light touch on the body, and being "woken" by a "presence". Any resemblance, no matter how exact, to phenomena associated with [[sleep]] and the sleep cycle is to be rejected.

==Ghost stories==
Especially around [[Halloween]], newspapers, television, and the [[internet]]s are flooded with supposedly factual ghost stories told from the point of view that ghosts are scary, no conventional explanation for them is likely, and witnesses couldn't possibly be exaggerating or embroidering their accounts. Supporting testimony from [[Ghost Hunters|scientific-sounding experts]] can make them seem all the more convincing. In truth, ghost stories are a form of largely formulaic storytelling that historians speculate evolved as a way of dealing with deep-rooted fears of death and dying, possibly inspired by cultural memories of 14<sup>th</sup> century Black Plague victims wrapped in white sheets. Many credulous "true tales" and "eyewitness reports" being published and passed around today are modern-day versions of traditional supernatural folklore that has been with us for hundreds of years.<ref>Goldstein, Grider, Thomas [http://digitalcommons.usu.edu/cgi/viewcontent.cgi?article=1017&context=usupress_pubs Haunting Experiences: Ghosts in Contemporary Folklore] Utah State University Press</ref>

==Stone Tape theory==
Somehow even ''weirder'' is the Stone Tape theory, put forth by [[archaeologist]]-turned-[[parapsychologist]] Thomas Charles Lethbridge, which surmises that ghost phenomena are recordings of traumatic experiences held in rocks instead of actual entities. No, seriously.

==Scientific explanations==
[[Image:Thanatos'_ghost.JPG|thumb|200px|A photograph of a "ghost" haunting Independence Hall, which is definitely not a camera flash.{{fact|joke}} <br/>]]

There is nothing to explain since there are no consistently observable phenomena to investigate. Hell, even if there was evidence, there isn't anything that can be used to experiment on such phenomena. The evidence assembled for the existence of ghosts is largely ''[[ad hoc]]'' — [[anecdotal]] and difficult (or impossible) to [[Reproducibility|duplicate]] or investigate further.

Explanations of ghosts supposedly dodging physical laws (like being semi-transparent or able to pass through walls) date back to Cambridge Platonist Henry Moore in the 17<sup>th</sup> century, who suggested that souls (and therefore ghosts) are essentially four-dimensional beings, an idea that Johann Karl Friedrich Zöllner promoted in the 19<sup>th</sup> century.<ref>Pickover, Cliff (2001)''Surfing Through Hyperspace'' Oxford University Press pg 123</ref>

Using Edwin Abbott Abbott's ''Flatland'' as his foundation, [[Carl Sagan]], in the print version of ''Cosmos'', stated:

{{cquote|"If a fourth-dimension creature existed it could, in our three-dimensional universe, appear and dematerialize at will, change shape remarkably, pluck us out of locked rooms, and make us appear from nowhere."|||Carl Sagan. ''Cosmos'' pg 219}}

The problem is that most ghost lovers go the easier 'doesn't follow physical laws' route and call it a day. In reality, they (though they don't realize it) mean 'doesn't follow ''three-dimensional'' physical laws'.<ref group=note>Some conceptions of ghosts ''do'' use the "four-dimensional space" rule or something close to it, though. For example, [[Dungeons and Dragons]] has an Ethereal Plane parallel to the Material Plane (i.e. the physical universe), which is where ghosts reside. And since the planes are parallel, it is possible for ghosts to "manifest" on the Material Plane to interact with it, though they are always at least partially on the Ethereal Plane and subject to its planar properties (laws of physics).</ref>

While there is no scientific evidence for ghosts, there is plenty of evidence about why people ''think'' they see ghosts. The complexities and limits of the human brain and perception and physical and environmental explanations can account for ghost sightings. For example, air pressure changes in a house can cause doors to slam, or humidity changes can cause boards to creak.

Apophenia (seeing meaningful patterns or connections in random or meaningless data) in conjunction with strong emotions can explain many ghost sightings. This combination was used by Carl Sagan to explain the [[Mars|Martian]] canals seen by Percival Lowell:

{{cquote|"There is no doubt that the Mars canals of Percival Lowell were of intelligent origin. The only question is which side of the telescope the intelligence was on. Where we have strong emotions, we're liable to fool ourselves."|||Carl Sagan, ''Cosmos''}}

Distorted shadows, reflections by not-immediately-obvious fixtures (or the flash of the camera itself), out-of-focus objects (the bug on a lens theory has been used to explain many ghost images in videotapes), and even particularities of the equipment itself, coupled to the desire to [[Belief|believe]], can explain many ghost sightings and even videos of ghosts. A photo taken inside Norwich Cathedral in 2015, purporting to show the ghost of a Bishop, and widely reported in UK tabloids, was, in fact, a blurry image of a wall section and one of the timbers supporting the aisle roof. Many such photos exist, where a poor photo causes a misidentification of a background object as a ghost. Were the image to be sharply focused, the illusion would disappear.

Other possible explanations include [[Hallucination|hallucinations]] due to a mental disorder, disease, or other reasons. Hallucinations, mainly auditory, are more common than many people realize. Another probable explanation could involve the effects of [[sleep paralysis]], especially as many sufferers experience the sensation of being held down by something, sometimes accompanied by terrifying hallucinations.

More intriguing is the possibility that ghosts and hauntings may be often due to infrasound, sound of a lower frequency than our ears can pick up.  It's known to give people a ''creepy'' feeling, or make someone feel like they're being watched.  Further, infrasound at 18Hz would match the symphonic resonance of the eye and distort one's vision enough that we might "see" things that aren't there, as the brain tries to make sense of inconsistent information being fed to it from the eyes.<ref>https://podcasts.apple.com/us/podcast/haunted-house-haunted-mind/id1293626269</ref>

Belief in ghosts may also come from the refusal to accept the finality of one's mortality, the possible absence of an [[afterlife]], and the inability to cope with the loss of a loved one. Ghosts are the "eternal spirit" of someone who has passed from the earthly realm and is not finally lodged in [[heaven]] (nor [[hell]]).

===St. Elmo's fire===
[[File:Elms Feuer aus Cockpit.JPG|right|thumb|150px|Spooky lights!]]
St. Elmo's fire (not {{wpl|St. Elmo's Fire (film)|that one}}) may look ghostly to some people, but it is a natural weather phenomenon with a scientific explanation. And one thing it isn't is fire (kinda, it is hot, though).

Like lightning, St. Elmo's fire is plasma or ionized air that emits a glow. However, it results not from the movement of charged particles from a cloud to the ground, but from a corona discharge caused by an imbalance in electrical charges. This imbalance is between the air and an object around it, and as a tapered surface will discharge at a lower voltage level, it occurs most often on the top of a steeple, mast, or plane wing.<ref>[https://web.archive.org/web/19991023012000/http://www.islandnet.com/~see/weather/elements/stelmo.htm Weather Elements: The Fire of St. Elmo]</ref>

==Religion==
There's a good amount of overlap between belief in ghosts and belief in [[religion]]. This is not a problem for ancestor-worshipping [[Taoism|Taoists]] or whatever-you-got-worshipping [[Wicca|neopagan witches]], but for the [[Abrahamic religions]], it's a pretty extreme [[heresy]]. The next time some [[Christian]] calls you a soulless [[atheist]] for not believing in ghosts because the [[Bible]]{{efn|actually [[Shakespeare]], of course}} says there's more than dreamed of in your [[philosophy]], tell him that you don't believe in ghosts because you don't want to go to [[hell]] and quote {{bible|Ephesians|6|11|12}} at him.{{efn|"Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. For we wrestle not against flesh and blood, but against {{wpl|Seven Spirits of God|principalities, against powers|,}} against the rulers of the darkness of this world, against spiritual wickedness in high places." Yeah, it doesn't sound as much like a warning against ghosts as some of the stuff in the [[Torah]] or the Epistles, but for some reason, it's the verse that Evangelicals usually use against occultists, and it sounds pretty weighty.}}

Whether or not ghosts exist, it's definitely both dangerous and [[sin]]ful to try to communicate with them. This is all over the [[Tanakh]], the [[New Testament]], and the [[Qur'an]]. And it's especially bad to pay necromancers to help you try. Leviticus 19 doesn't quite say that [[John Edward]] is the biggest douche in the universe, but it does say that you'll be "defiled" just by associating with him and those like him. And Deuteronomy 18 makes it clear that he's an [[abomination]] — as bad as sacrificing to the wrong god, [[homosexuality|being gay]], or even [[God Hates Shrimp|eating shrimp]].{{efn|But we don't have to stone him to death; he's so bad that God will drive him out, so we don't have to.}}

But do ghosts exist? The [[Catholics]] say we can't be sure,{{efn|Catholic Answers used to say that even ''trying'' to answer yes or no would be engaging in occultiscm.}} and the [[Mormons]] give conflicting answers… but most [[Evangelical Christians]], many mainline [[Protestant]] churches, and most branches of [[Islam]] say no. If you see your departed mother or a famous silent-film star floating through the walls, what you're actually seeing are [[Satan]]'s [[evil]] spirits (for Christians), [[djinn]] (for Muslims), or Cybermen (for Whovians). So, the warnings in the Bible and Qur'an against talking to ghosts are there because it's pretty dangerous to try to communicate with a deceitful evil spirit while convincing yourself that it's grandpa. Plus, to most Christians and Muslims, survival after death is bodily [[resurrection]], not floating around as a spirit — or "[[ectoplasm]]", whatever that is. That's central to their [[theology]].{{efn|After all, what's the point of hell without physical bodies to endure the infinite [[Snuff film|snuff porn]]?}} Not every Abrahamic sect agrees, but they mostly have their own reason to doubt ghosts.{{efn|One viewpoint in Judaism, as expressed by [[Maimonides]], is that you actually are nonphysical in the afterlife, or at least for the first year — but that means you cannot be seen by the living, and can only communicate with them in dreams, so still no ghosts.}}{{efn|[[Seventh-day Adventism|Seventh-Day Adventists]], [[Jehovah's Witnesses]], and a few others believe you persist as a nonphysical soul after death — but that's because your soul is "asleep" until the resurrection, not running around going "woooooo!"}}

And even if ghosts do exist, they definitely aren't haunting houses.{{efn|{{bible|Job|7|9}} "… he who goes down to the grave does not come up. He shall never return to his house, Nor shall his place know him anymore."}} Or taking care of unfinished business.{{efn|{{bible|Psalm|146|4}}: "When his breath departs, he returns to the earth; on that very day his plans perish."}} Or helping and/or getting revenge on the living.{{efn|{{bible|Ecclesiastes|9|5|6}} "But the dead know nothing, and they have no more reward, For the memory of them is forgotten. Also their love, their hatred, and their envy have now perished; nevermore will they have a share in anything done under the sun."}} The only reason for ghostly persistence the Bible doesn't explicitly rule out is Whoopi Goldberg sex.

What about the ghosts of Elijah and [[Moses]]? Besides the Transfiguration being a special case and [[Peter]] would hardly set up tents for a couple of floating blobs of transparent ectoplasm, Elijah never died,{{efn|He was called bodily up to heaven; it's a big deal, especially in Christianity.}} so how could he be a ghost?

OK, what about the Witch
-King
 of Endor summoning the dead [[prophet]] Samuel for King Saul?{{efn|{{bible|1 Samuel|28|11}}}} First, the whole point of the story was to demonstrate how far Saul had fallen and why God had to kill him and anoint a new King, so he's probably not an example you want to follow unless you want a very angry Spirit of Elohim to show up and judge you in person. But here are the major explanations:
*Evangelical, [[Calvinist]], [[Anglican]], Catholic: Saul was talking to an evil spirit pretending to be Samuel.
*[[Lutheran]]: Saul was talking to Satan, pretending to be Samuel.
*[[Eastern Orthodox]]: It was a [[hoax]] by the [[witch]] (who's called a ventriloquist in the Greek translation).
*Mainstream Jewish tradition: God broke the universe's rules to let Saul talk to Samuel's spirit just so he could punish Saul for doing so.
*Minority Jewish tradition: The Witch actually opened a physical portal to {{wpl|Sheol||,}} and what Saul spoke to was the physically resurrected Samuel.

So ghosts probably aren't real — but ''Doom'' is, so be careful.
