According to Dr. Anil Aggrawal in his 2009 book Forensic and Medico-legal Aspects of Sexual Crimes and Unusual Sexual Practices nyctophilia is a sexual paraphilia where the individual derives sexual pleasure and arousal by a “love of night”. In the same book, Aggrawal defines similar (if not the same conditions) including scotophilia (“turned on by darkness”), lygophilia (“love of darkness”) and achluophilia (“arousal from darkness”). Another related condition is arguably amaurophilia (“arousal by a partner who is blind or unable to see due to artificial means such as being blindfolded or having sex in total darkness”, a paraphilia that I examined in depth in a previous blog). Other sources (such as Dr. Brenda Love’s Encyclopedia of Unusual Sex Practices doesn’t mention any of these, apart from amaurophilia) whereas other medical dictionaries conflate darkness and night together and define nyctophilia as a “preference for the night or darkness. Also called scotophilia”.
As far as I can ascertain, there is no empirical research on this topic at all. There are many references to the similar sounding scopophilia (viewed by many as another term for ‘voyeurism’) but as Dr. Aggrawal notes:
“Several terms have been used as synonyms of voyeurism, although some writers have constantly pointed out subtle differences. The terms scopophilia and scoptophilia are taken as synonyms to voyeurism by most writers. However, others have pointed out a minor difference. If the victim is unsuspecting and non-consenting, the act is voyeurism, but if the other party is consenting, the act is scopophilia or scoptophilia. Furthermore, if the person watched is in the act of disrobing, or nude, the act is voyeurism, but if the person watched is engaged in sex, the act is either mixoscopia (if the watched person is the voyeur’s lover) or allopellia (if the watched persons are complete strangers)”.
The reason I mention this is because in a paper by Dr. Patrick Mahony on voyeurism in a 1989 issue Journal of the American Psychoanalytic Association noted that the “alternate spelling scoptophilia, preferred by some of the older German psychoanalysts, must not be confused with scotophilia or love of darkness”. This appears to have happened in other academic papers I found directly referring to ‘scotophilia’. For instance, one paper dating back almost 70 years was that of Dr. F.S. Caprio who wrote a paper entitled ‘Scotophilia–exhibitionism: A case report’ in the Journal of Clinical and Experimental Psychopathology but it was actually a paper about voyeurism. More specifically, the paper reported the cases of a mother and son who constantly watched residents for sexual arousal in the mother’s rooming house via drilled holes in the wall. A 1966 theoretical review paper by Dr. Jerome Sattler on embarrassment and blushing published in the Journal of Social Psychology claimed that “stage-fright and erythrophobia [fear of blushing] are not simply expressions of the warding off of heightened exhibitionism and scotophilia but also develop as a result of previous instinctual conflict”. Here again, scotophilia appears to be a synonym for voyeurism rather than a sexual love of darkness.
I was pleasantly surprised to find dozens of references to nyctophilia in the scientific literature but the overwhelming majority of papers were biological in origin and all referred to non-human species. For instance, a recent 2016 paper Dr. Luis Espinasa and colleagues in the journal Subterranean Biology reported that cave amphipods are eyeless troglobitic crustaceans found in caves located in the Northeastern (Allegheny) region of the United States and who “exhibit nyctophilia” (literally meaning they love darkness, and has absolutely nothing sexual whatsoever).
I only managed to find one non-biological academic reference on nyctophilia and this was a 1994 paper by Dr. Lewis Lawson in the journal Papers on Language and Literature. In actuality, the use of the word ‘nyctophilia’ was mentioned in passing and noted that the term was defined by psychoanalyst Bertram Lewin as “an erotic pleasure in darkness, which enters as a wish-fulfillment element on fantasies of being in the ‘womb,’ or more properly, as the German word Mutterlieb suggests, of being in the mother’s body”. I was unable to track down the original source so I don’t know the context in which Lewin used the word but the definition is certainly used in a sexual sense rather than the general ‘love of darkness’ used in the biologically-based papers.
In a more general search on the internet, located dedicated photographic sites for nyctophilia, a number of fictional books with the title of Nyctophilia (such as the novel by Welsh author K.A. Hambly), and even the name of a 2014 film (although details about it are sketchy to say the least). I also came across one first-person account of nyctophilia online from someone who has written a number of different articles about the condition such as ‘What is nyctophilia?’, ‘What is it like to have nytophilia?’ and ‘Everything you wanted to know about nyctophilia symptoms’. However, detailed reading of these articles suggests that any sexual element is secondary to a general love of darkness. Here are a few extracts from the articles:
Extract 1: “I have a confession to make. I am a nyctophiliac…Well, a lot of people have told me that I am an insomniac. An insomniac is someone who has difficulty sleeping at night. But I have realized over time that I am not just an insomniac. Insomnia is a physical condition, not a psychological one. Nyctophilia, on the other hand, is purely a psychological condition. Many say that nyctophiliacs are sexually aroused by the dark. Is that true? Well, yes and no. I like darkness, but I am not always sexually aroused by it. I just love it for what it is. It gives me a sense of relief and it makes me happy”.
Extract 2: “To help you understand nyctophilia symptoms, [here] I reveal some uncomfortable details of my life. Every night, I try to sleep at 10 pm. I take sleeping pills such as Klonopin and get myself a good book to read. When I do fall asleep, at around 10:30 pm or 10:45 pm, I find myself waking up at 12:00 am sharp, as fresh as the day, as though I’ve been asleep for 9 hours. I am wide awake at this time and no matter what I do, I cannot go to sleep. Unlike an insomniac, who would turn the lights on and perhaps watch TV, that’s the last thing on my mind. I just want to sit in the bedroom chair in the dark, all alone, with just darkness as my company. I love the darkness. It makes me happy. I feel a sense of relief as I sit in the dark and listen to the sound of the clock ticking by. I know it’s not good for me to stay awake like this, like a ghost, in complete darkness. I tell that to myself several times and often I try my very best to sleep. That is when I get those dreams. Those horrible dreams. The nightmares. I find myself in impossible situations, either getting tortured like Mel Gibson in Braveheart or dying of a dreadful disease, like a child affected by the Ebola virus in Africa”.
Extract 3: “There isn’t much of an awareness of nyctophilia, or nyctophilia symptoms, out there on the Web…The UrbanDictionnary.com defines nyctophilia as ‘The love of darkness or night, or feeling like you belong in the dark” and adds that the condition ‘usually applies to those who often feel sadness!’ Nyctophilia is a condition that makes you want to sit in the dark all by yourself late at night, wide awake…You may wander off late at night in the dark. This will get you in trouble with the authorities, who do not really understand the nyctophilia meaning and cannot even comprehend how you feel. So you may get mistaken for a sex addict or a pervert, or possibly a criminal. Your neighbors would avoid you and report you to the law enforcement agencies. They would want you to leave the neighborhood and move somewhere else. They would feel distinctly uncomfortable about your condition and word would get around about the fact that you stay up all night in the dark, basically doing nothing”.
Extract 4: “There are many who say that nyctophialiacs find darkness sexually arousing. They compare the condition to a form of sex addiction. Indeed, have been given medication for sex addiction, such as GnRH, a long lasting gonadotropin releasing hormone that suppresses sexual desires. If you feel that you have any of the nyctophilia symptoms…it is important to get yourself treated by a qualified psychiatrist, preferably someone who has experience of working with modern or unusual psychiatric conditions. Take the medications that are suggested to you and ask support from your friends and family”
In all the reading I have done on this topic, there appears to be very little genuine evidence that scotophilia and nyctophilia exist, and if the condition does exist, few people appear to suffer major problems as a consequence, unless their love of the dark leaves the person feeling so sleep-deprived that it interferes with their day-to-day functioning. Maybe this condition is a sub-type of insomnia but that the underlying reasons for not going to sleep are very different from the usual reasons for not being able to sleep.

Displeasures of the flesh: A brief look at anthropophagolagnia and paraphilic behaviour in serial killers
In previous blogs I have examined the psychology of sexual cannibalism and erotophonophilia (aka ‘lust murder’) as well as an article that I wrote on serial killers that collect their victims’ body parts as ‘trophies’. One very rare sub-type of both sexual cannibalism and erotophonophilia is anthropophagolagnia. This particular type of sexual paraphilia has been defined by Dr Anil Aggrawal as the paraphilia of “rape with cannibalism” and by the Right Diagnosis website as “sexual urges, preferences or fantasies involving raping and then cannibalizing the victim”.
The Listaholic website goes as far to say that anthropophagolagnia is one of the ten “most bizarre sexual fetishes on earth” claiming that serial killer is the “poster boy” for these “twisted” individuals. Other serial killers that might be classed as anthropophagolagniacs include Albert Fish, Peter Kirsten, Ottis Toole and Ed Gein. However, there also appear to be cases of what I would call ‘systematic anthropophagolagnia’ if the extract I found online is true:
“While it is easy to dismiss one case as stemming from some sort of neurological aberrations in the participants, we also see sexualized cannibalism in modern day Africa. In the early 2000s in Congo, rape and cannibalism were reported to coincide sporadically across the region. The claims are backed by a UN investigation into the phenomena…Rebels would go into villages and rape the women and children, then dismember them alive while eating their flesh. There are many reports of family members being forced to eat the flesh of other murdered family members after being raped…The men committing these atrocities do not have any neurological aberrations, they simply have the power to exercise this behavior. While cannibalism has been practiced in Africa as part of spiritual traditions for centuries, sadistic sexualized torture is not part of that tradition. So why add it in? Presumably the rebels didn’t all happen to be born child rapists either, yet raping children is part of their terror campaign and they must be able to achieve an erection to carry out the task, and so it must be assumed they learned to like it”.
Last year, I also read about 40-year old preacher Stephen Tari, the leader of a 6,000-strong cannibal rape cult in Papua New Guinea. He was in prison following his conviction for a brutal rape but escaped (only to be killed by people from his village in retaliation for the cannibalistic rape murders he had committed). As a report in The Independent noted:
“[Tari] had previously been accused of raping, murdering and eating three girls in front of their traumatised mothers…The charismatic cult leader, who wore white robes and is said to have regularly drunk the blood of his ‘flower girls’, quickly returned to his home village of Gal after [a prison] escape, but could only manage six months before killing yet again…It has not yet been established if the murdered woman was killed as part of a blood sacrifice, but it is considered likely as Tari was said to have been attempting to resurrect his cult following the spell in prison”.
Dr. Eric Hickey (in his book Serial Murderers and Their Victims) notes that paraphilic behaviour is very common among those that commit sexual crimes (and that more than one is often present) but that the two activities (sex offending and paraphilias) may be two independent constructs and that one does not necessarily affect the other. In fact he notes that:
“Rather than paraphilia being caused by sexual pathology, they may be better understood as one of many forms of general social deviance…For the male serial killer, the paraphilia engaged in usually has escalated from softer forms to those that are considered not only criminal but violent as well. They range from unusual to incredibly bizarre and disgusting. As paraphilia develop, men affected by them often engage in several over a period of time. Most men who engage in paraphilia often exhibit three or four different forms, some of them simultaneously. For those with violent tendencies, soft paraphilia can quickly lead to experimentation with hardcore paraphilia that often involves the harming of others in sexual ways. For example, some paraphilic offenders prefer to stalk and sexually assault their victims in stores and other public places without getting caught. The thrill of hunting an unsuspecting victim contributes to sexually arousing the offender”.
Hickey asserts that anthropophagolagnia is one of the so-called ‘attack paraphilias’ (as opposed to the ‘preparatory paraphilias’). Attack paraphilias are described by Hickey as being sexually violent (towards other individuals including children in extreme circumstances). Preparatory paraphilias are defined by Hickey as those “that have been found as part of the lust killer’s sexual fantasies and activities” (including those that display anthropophagolagnia). However, Hickey notes that individuals that engage in preparatory paraphilias do not necessarily go on to become serial killers. He then goes on to say:
“The process of sexual fantasy development may include stealing items from victims. Burglary, although generally considered to be a property crime, also is sometimes a property crime for sexual purposes. Stealing underwear, toiletries, hair clippings, photographs, and other personal items provides the offender with souvenirs for him to fantasize over”.
Some of the examples Hickey cites are both revealing and psychologically interesting:
“One offender noted how he would climax each time he entered a victim’s home through a window. The thought of being alone with people sleeping in the house had become deeply eroticized. Another offender likes to break into homes and watch victims sleep. He eventually will touch the victim and will only leave when she begins to scream. He ‘began’ his sexual acting out as a voyeur. This paraphilic process was also examined by Purcell and Arrigo (2001), who note that the process consists of mutually interactive elements: paraphilic stimuli and fantasy; orgasmic conditioning process; and facilitators (drugs, alcohol, and pornography). The probability of the offender harming a victim is extremely high given the progressive nature of his sexual fantasies”.
Along with anthropophagolagnia, other ‘attack paraphilias’ that have been associated with serial killers include amokoscisia (sexual arousal or sexual frenzy from a desire to slash or mutilate other individuals [typically women]), anophelorastia (sexual arousal from defiling or ravaging another individual), biastophilia (sexual arousal from violently raping other individuals; also called raptophilia), dippoldism (sexual arousal from abusing children, typically in the form of spanking and corporal punishment), necrophilia (sexual arousal from having sex with acts with dead individuals), paedophilia (sexual arousal from having sex with minors typically via manipulation and grooming), and sexual sadism (empowerment and sexual arousal derived from inflicting pain and/or injuring other individuals).
The ‘preparatory paraphilias’ that typically precede serial killing and attack paraphilias such as anthropophagolagnia include agonophilia (sexual arousal caused by a sexual partner pretending to struggle), altocalciphilia (sexual arousal from high-heeled shoes), autonecrophilia (sexual arousal by imagining oneself as a dead person), exhibitionism (exposing genitals to inappropriate and/or non-consenting people for sexual arousal), frottage (sexual arousal from rubbing up against the body against a sexual partner or object), gerontophilia (sexual arousal from someone whose age is older and that of a different generation), hebephilia (men that are sexually aroused by aroused by teenagers), kleptolagnia (sexual arousal from stealing), retifism (sexual arousal from shoes), scatophilia (sexual arousal via making telephone calls, using vulgar language, and/or trying to elicit a reaction from the other party), scoptophilia (sexual arousal by watching others [typically engaged in sexual behaviour] without their consent, and more usually referred to as voyeurism), and somnophilia (sexual arousal from fondling strangers in their sleep). The multiplicity of co-existent paraphilias (including anthropophagolagnia) is highlighted by the Wikipedia entry on Jeffrey Dahmer:
“Dahmer readily admitted to having engaged in a number of paraphilic behaviors, including necrophilia, exhibitionism, hebephilia, fetishism, pygmalionism, and erotophonophilia. He is also known to have several partialisms, including anthropophagy (also known as cannibalism). One particular focus of Dahmer’s partialism was the victim’s chest area. By his own admission, what caught his attention to Steven Hicks hitchhiking in 1978 was the fact the youth was bare-chested; he also conceded it was possible that his viewing the exposed chest of Steven Tuomi in 1987 while in a drunken stupor may have led him to unsuccessfully attempt to tear Tuomi’s heart from his chest. Moreover, almost all the murders Dahmer committed from 1990 onwards involved a ritual of posing the victims’ bodies in suggestive positions – many pictures taken prior to dismemberment depict the victims’ bodies with the chest thrust outwards. Dahmer also derived sexual pleasure from the viscera of his victims; he would often masturbate and ejaculate into the body cavity and at other times, literally used the internal organs as a masturbatory aid”.
Almost nothing is known empirically about anthropophagolagnia except that it is very rare and that almost all information about it comes from serial killers that have been caught. Explanations for the development of anthropophagolagnia can only be speculated but are likely to be no different from the development of other paraphilic behaviour. Hickey (citing Irwin Sarason and Barbara Sarason’s Abnormal Psychology textbook) notes five key explanations for the development of paraphilias (reproduced below verbatim):
- Psychodynamic – paraphilic behavior as a manifestation of unresolved conflicts during psychosexual development;
- Behavioral – paraphilia is developed through conditioning, modeling, reinforcement, punishment, and rewards, the same process that normal sexual activity is learned;
- Cognitive – paraphilia become substitutes for appropriate social and sexual functioning or the inability to develop satisfying marital relationships;
- Biological – heredity, prenatal hormone environment, and factors contributing to gender identity can facilitate paraphilic interests. Other explanations are linked to brain malfunctioning and chromosomal abnormalities;
- Interactional – that development of paraphilia is a process that results from psychodynamic, behavioral, cognitive, and biological factors.
As an eclectic, I favour the interactional explanation for the existence of anthropophagolagnia but also believe that the most important influences are the behavioural aspects via classical and operant conditioning processes.

In the 2000 film American Psycho, the anti-hero Patrick Bateman (played by Christian Bale) contains a scene in which while having sex with two female escorts, looks at himself in the mirror admiringly. Even when one of the escort girls tries to attract his attention, he seemingly prefers to look at himself rather than the women he is making love to. Quite clearly a narcissist, Bateman may have also been a kataptronophile. According to Dr. Anil Aggrawal’s 2009 book Forensic and Medico-legal Aspects of Sexual Crimes and Unusual Sexual Practices, katoptronophilia is a sexual paraphilia defined as sexual pleasure and arousal from having sex in front of mirrors.
Having said that, somewhat confusingly, Aggrawal also says that individuals who derive sexual arousal “from looking at oneself in a mirror [and] arousal from image in mirrors” is called spectrophilia. (However, I examined this in a previous blog and most credible sources state that spectrophilia relates to those who derive sexual arousal and pleasure from having sex or sexual thoughts about ghosts). A short online article on katoptronophilia on the Wikipedia website goes a little further and defines it as:
“…a paraphilia for mirrors (the Greek word for mirror is katoptron). It may include activities such as having sex in front of mirrors, masturbating in front of mirrors, enacting other paraphilias in front of a mirror, having an orgy in front of a mirror, or enacting stripping fetishism in front of mirrors. Enacting katoptronophiliac fantasies may involve constructing environments for erotic activity in which one is completely surrounded by mirrors, sometimes including even on the ceiling. A person who is a katoptronophiliac may put mirrors all over their house so they can have sex in any room in the house”.
On first look, katoptronophilia appears to be a sub-type of voyeurism where the key distinguishing feature is the use of mirrors as part of the voyeuristic act. However, voyeurism is usually defined as the act of gaining sexual arousal from the watching of others either naked and/or engaging in sexual behaviour. I stressed the word ‘others’ as katoptronophila involves the watching of oneself having sex via the use of mirrors. Technically, kataptronophilia is a sub-type of scoptophilia (sometimes called scopophilia). According to Dr. George Pranzarone in his 2000 Dictionary of Sexology, scoptophilia/scopophilia is
“A paraphilia of the solicitational [and] allurative type in which sexuoerotic arousal and facilitation or attainment of orgasm are responsive to, and contingent on watching others engaging in sexual activity, including sexual intercourse [from Greek, skopein, to view + -philia]. The condition in which a person is dependent on looking at sexual organs and watching their coital performance in order to obtain erotic arousal and facilitate and achieve orgasm. It is not surreptitious, as in voyeurism. The reciprocal paraphilic condition is sometimes also referred to as scoptophilia; or by its own name, autagonistophilia. Synonyms, mixophilia; mixoscopia; scopophilia”.
Just complicate things a little further, many online definitions of mixophilia (which as in the definition by Dr. Pranzarone above appears to be another word for scoptophilia) often mention mirrors in the definitions. For instance, the Fetish List website defines mixophilia as gaining sexual arousal and pleasure from watching “their partner or themselves engage in sexual activity. Usually this means watching themselves in a mirror”. This is similar to the definition for mixophilia in the online Gay Slang Dictionary that notes:
“A person with this fetish [mixophilia] likes to watch his partner or the both of them engage in sexual activity. Usually this means watching themselves perform in a mirror. A common theme in gay porn pictures is the presence of a mirror in which part or all of the action is reflected”
I’ve yet to come across a single academic article on the topic and most of the theorizing is speculative to say the least. In 2003, Mark Pendergrast published his cultural history of mirrors (Mirror, Mirror: A History of the Human Love Affair with Reflection), but did not specifically examine katoptronophilia (although did mention the sexual use of mirrors). The one thing I learned was that the Etruscans [an ancient Italian civilization originating around what is now known as Tuscany] often featured sex scenes painted on the back of their mirrors). In relation to why katoptronophilia exists, one online snippet I came across claimed that:
“Theories suggest that katoptronophilia is fed from a basal narcissistic instinct. It is a combination of narcissism and degradation and a feeling of over powering dominance. It’s like watching a live porno of yourself. The most advanced stage of voyeur there is”
This appears to be somewhat corroborated by the Wikipedia entry (and the fictionalized account that opened this blog) that notes that:
“Many pornographic films show porn stars having sex in front of mirrors. Many people enjoy having sex in front of mirrors and have mirrors in their bedrooms in which they can watch themselves have sex. They sometimes engage in this activity for their personal enjoyment. On a deeper level this could relate to the person’s need to reflect and critique themselves, and also being on a mental state of narcissism. The person often is solely absorbed in themselves and likes to watch their actions so as to admire”.
A 2007 online article on kataptronophilia at the Journals of an Intelsexual website argues that the fetish is evolving and that “technology is also expanding on this fetish; live stream cameras, multiple cameras, big screen monitors…the possibilities are limitless”. I’m not convinced that evolving technology providing more ways to watch yourself having sex is actually katoptronophilia as the key distinguishing feature of the paraphilia is the use of mirrors (not the watching of yourself). I seriously doubt if this type of paraphilic behaviour (and I have some doubts as to whether it is a paraphilic behaviour anyway) will ever be the subject of serious academic research as it’s highly unlikely that such behaviour is problematic un any way.
