La littérature suggère que le sommeil paradoxal joue un rôle dans l'intégration associative de la mémoire émotionnelle. De plus, les rêves en sommeil paradoxal, en particulier leur nature bizarre et émotionnelle, semblent refléter cette fonction associative et émotionnelle du sommeil paradoxal. La conséquence des cauchemars fréquents sur ce processus est inconnue, bien que le réveil provoqué par un cauchemar semble interférer avec les fonctions du sommeil paradoxal. Le premier objectif de cette thèse était de reproduire conceptuellement des recherches antérieures démontrant que le sommeil paradoxal permet un accès hyper-associatif à la mémoire. L'utilisation d'une sieste diurne nous a permis d'évaluer les effets du sommeil paradoxal, comparativement au sommeil lent et à l’éveil, sur la performance des participants à une tâche sémantique mesurant « associational breadth » (AB). Les résultats ont montré que seuls les sujets réveillés en sommeil paradoxal ont répondu avec des associations atypiques, ce qui suggère que le sommeil paradoxal est spécifique dans sa capacité à intégrer les traces de la mémoire émotionnelle (article 1). En outre, les rapports de rêve en sommeil paradoxal étaient plus bizarres que ceux en sommeil lent, et plus intenses émotionnellement ; ces attributs semblent refléter la nature associative et émotionnelle du sommeil paradoxal (article 2). Le deuxième objectif de la thèse était de préciser si et comment le traitement de la mémoire émotionnelle en sommeil paradoxal est altéré dans le Trouble de cauchemars fréquents (NM). En utilisant le même protocole, nos résultats ont montré que les participants NM avaient des résultats plus élevés avant une sieste, ce qui correspond aux observations antérieures voulant que les personnes souffrant de cauchemars soient plus créatives. Après le sommeil paradoxal, les deux groupes, NM et CTL, ont montré des changements similaires dans leur accès associatif, avec des résultats AB-négatif plus bas et AB-positif plus grands. Une semaine plus tard, seul les participants NM a maintenu ce changement dans leur réseau sémantique (article 3). Ces résultats suggèrent qu’au fil du temps, les cauchemars peuvent interférer avec l'intégration de la mémoire émotionnelle pendant le sommeil paradoxal. En ce qui concerne l'imagerie, les participants NM avaient plus de bizarrerie et plus d’émotion positive, mais pas négative, dans leurs rêveries (article 4). Ces attributs intensifiés suggèrent à nouveau que les participants NM sont plus imaginatifs et créatifs à l’éveil. Dans l'ensemble, les résultats confirment le rôle du sommeil paradoxal dans l'intégration associative de la mémoire émotionnelle. Cependant, nos résultats concernant le Trouble de cauchemars ne sont pas entièrement en accord avec les théories suggérant que les cauchemars sont dysfonctionnels. Le groupe NM a montré plus d’associativité émotionnelle, de même que plus d'imagerie positive et bizarre à l’éveil. Nous proposons donc une nouvelle théorie de sensibilité environnementale associée au Trouble de cauchemar, suggérant qu'une sensibilité accrue à une gamme de contextes environnementaux sous-tendrait les symptômes uniques et la richesse imaginative observés chez les personnes souffrant de cauchemars fréquents. Bien que davantage de recherches doivent être faites, il est possible que ces personnes puissent bénéficier e milieux favorables, et qu’elles puissent avoir un avantage adaptatif à l'égard de l'expression créative, ce qui est particulièrement pertinent lorsque l'on considère leur pronostic et les différents types de traitements. / Existing literature suggests that REM sleep plays a role in the associative integration of emotional memory, and that attributes of dreams during REM sleep, particularly their bizarre and emotional nature, either reflect or even influence this associative and emotional function. The consequence of frequent nightmares on this process is unknown, although, the experience of a nightmare suggests an associative restriction imposed by intense negative emotion, consistent with research showing that negative affect tends to restrict cognitive flexibility in wake. This is consistent with existing theories of nightmare function, largely purporting that nightmares reflect temporary failures in emotion regulation. The first objective of the thesis was to conceptually replicate prior research portraying REM sleep as enabling increased associative access to emotional memory. The use of a daytime nap allowed us to assess the effects of REM sleep, compared to both NREM sleep and waking, on participant performance on a novel task measuring Associational Breadth (AB). Results showed that only those subjects awakened from REM sleep responded with atypical emotional word associations, suggesting that REM is specific in its capacity to broadly integrate emotional memory traces (article 1). Further, REM dream reports were more bizarre than both NREM dreams and waking daydreams, and more emotionally intense than NREM dreams; these attributes are thought to reflect the hyper-associative and emotional nature of REM sleep (article 2). The second objective was to clarify whether and how REM sleep-dependent emotional memory processing is altered in frequent nightmares sufferers. Using a similar nap protocol, our results showed that NM participants had higher baseline AB in response to emotional cue-words, contrary to predictions, but nonetheless corresponding with anecdotal reports of heightened creativity. Following REM sleep, both NM and CTL groups showed similar changes in associative access to emotional cue-words, with negative AB being restricted and positive AB being broadened; one week later, the NM group alone maintained this altered pattern of emotional semantic access (article 3). This finding suggests that, over time, nightmares may interfere with REM sleep-dependent emotional memory integration. Regarding imagery, the NM participants had heightened bizarreness, and positive, but not negative, imagery in their daydreams, but not their dreams (article 4), mirroring our AB finding that the NM group had significantly higher emotional associativity in wake, although patterns of associativity following a REM sleep nap did not differ between groups. Overall, findings support a role of REM sleep in the associative integration of emotional memory. However, our findings regarding nightmare sufferers are not entirely consistent with views that nightmares are associated with dysfunctional emotional memory processing. Although they did show a prolonged priming effect suggestive of inadequate emotion regulation, they also showed heightened semantic associativity and vivid positive imagery in wake. We therefore propose a novel Environmental Sensitivity framework for the study of nightmare sufferers, claiming that an increased sensitivity to a range of environmental contexts, not only negative contexts, underlies the unique symptoms and imaginative richness seen in frequent nightmare sufferers. Although further empirical research exploring potentially adaptive traits or sensitivity to positive contexts in nightmare sufferers is needed, the possibility that these individuals may benefit especially from supportive environments, and may have heightened creativity and semantic associativity, is particularly relevant when considering prognosis and treatment approaches.

Il y a une longue histoire derrière l’intérêt porté pour les rêves lucides –conscience de rêver pendant un rêve– datant de l’époque de la Grèce antique. La compréhension du rêve lucide a d’abord reposée sur des observations personnelles de certains individus ayant eux-mêmes expérimentés leurs propres rêves lucides. La découverte de l’inconscient, de même que celle du sommeil paradoxal (SP), a grandement contribué à l’essor du rêve lucide, qui a finalement constitué l’objet d’étude de plusieurs recherches empiriques, dont celles menées par le groupe de Stanford, qui est l’un des premiers à avoir évalué la capacité des rêveurs à signaler leurs rêves lucides à l’aide de différents mouvements du corps, en temps réel. Le rêve lucide est un phénomène prévalent, comprenant de nombreuses dimensions, allant de la conscience de soi jusqu’au contrôle sur le contenu du rêve. Certains auteurs ont également parlé du rêve lucide en tant qu’état mental hybride, combinant des caractéristiques des rêves survenant en SP et d’autres caractéristiques propres à l’éveil. De plus, il s’avère que les individus rapportant des rêves lucides fréquemment présentent des caractéristiques psychologiques particulières, sans compter les corrélats physiologiques mesurables qui ont également été associés aux rêves lucides, de même que des corrélats neurophysiologiques. Certains auteurs se sont questionnés sur les différentes façons d’induire des rêves lucides en sommeil. Les techniques proposées sont nombreuses et diversifiées, allant des techniques comportementales aux techniques de stimulation électrique. À cet effet, deux études ont utilisé la stimulation transcrânienne par courant direct (tDCS) (Stumbrys, Erlacher, & Schredl, 2013) et alternatif (tACS) (Voss et al., 2014) dans les régions frontales pendant le SP, montrant une association entre l’augmentation de la conscience de soi dans les rêves et l’activité gamma fronto-temporale. Toutefois, ces études renferment plusieurs faiblesses méthodologiques. Nous avons donc tenté de reproduire ces résultats considérables en appliquant la tACS en SP dans les régions frontales pendant 2.5 min à une fréquence de 40 Hz lors de siestes matinales –favorisant des périodes riches en SP– et en utilisant des tests statistiques plus conservateurs ainsi que des mouvements oculaires pour signaler la lucidité. Pour s’y faire, nous avons recruté 33 sujets dans une étude randomisée à simple aveugle dans laquelle la tACS a été appliquée (STIM) ou non (SHAM) en SP. Les sujets ont été réveillés 3 min après la fin de la STIM ou du SHAM pour répondre à un journal de rêves et une échelle évaluant le degré de lucidité contenu dans les rêves. Bien que plusieurs signaux de lucidité ont été observés, ces derniers se sont produits dans les deux conditions expérimentales, et ce, sans différence significative. L’auto-évaluation du contenu des rêves ne différait pas non plus entre les conditions. Par conséquent, les résultats de la présente étude ne permettent pas de conclure que la tACS appliquée à une fréquence de 40 Hz en SP engendre plus de rêves lucides signalés en temps réel, un plus grand nombre de rêves lucides tels que définis par la LuCiD Scale et des scores plus élevés aux facteurs de cette même échelle. Plusieurs considérations méthodologiques peuvent avoir jouer un rôle dans la production de rêves lucides en sommeil, tels que les critères de recrutement, la pratique des signaux de lucidité et les effets indirects de la tACS, et avoir masqué l’effet de la tACS, qui, dû à son effet sans doute minime, n’a peut-être pas été en mesure d’influencer significativement la production de rêves lucides. Somme toute, plusieurs sujets ont été en mesure de signaler ou de rapporter des rêves lucides dans le cadre de cette étude, ce pourquoi il serait intéressant d’étudier davantage les différentes applications des rêves lucides, autant dans le but d’accroitre nos connaissances sur les rêves et les théories de la conscience que pour développer de potentiels outils cliniques. / There is a long history of interest in lucid dreaming–the awareness of dreaming while dreaming–from the time of ancient Greece. The understanding of lucid dreaming was initially based on personal observations of certain individuals who had themselves experienced lucid dreams. Discovery of the unconscious, as well as rapid-eye-movement (REM) sleep, greatly contributed to the rise of interest in lucid dreaming, which finally became the object of several empirical studies. The Stanford group is one of the first to have conducted laboratory studies specifically on lucid dreams assessing, among other attributes, the ability of dreamers to signal their lucid dreams with different body movements in real-time. Lucid dreaming is a prevalent phenomenon, comprising many dimensions, ranging from self-awareness to control over dream content. Some authors have also described lucid dreaming as a hybrid mental state, mixing REM dreaming and wakefulness characteristics. Moreover, frequent lucid dreamers display certain psychological characteristics, such as high creativity, an internal locus of control, and increases in several cognitive functions. Lucid dreaming has measurable physiological and neurophysiological correlates. Some authors have speculated about the different ways to induce lucid dreams during sleep. The proposed techniques are many and varied, ranging from behavioral techniques to electrical stimulation techniques. Critically, two studies employing frontal transcranial direct (tDC) (Stumbrys et al., 2013) and alternating (tAC) current stimulation (Voss et al., 2014) during REM sleep, have shown an association between increased self-awareness in dreams and fronto-temporal gamma electroencephalographic activity. However, these studies suffer from several methodological weaknesses. We attempted to replicate these important findings using frontal tAC stimulation during morning, REM-rich naps, real-time signal verification and more appropriate conservative statistical tests. We recruited 33 subjects in a single-blind randomized group study in which tAC stimulation was applied (STIM) or not (SHAM) during the REM sleep of a morning nap. During the STIM condition, we applied frontal 40 Hz tAC stimulation during REM sleep for 2.5 min. Subjects were awakened 3 min after stimulation offset for dream reporting and administration of a scale to assess dream lucidity. Although several episodes of signal-verified dream consciousness were observed, these were equally frequent in SHAM and STIM conditions. Self-ratings of dream content also did not distinguish conditions. Therefore, the findings of the present study do not indicate that frontal gamma stimulation increases dreamed self-awareness as measured by real-time signal-verified lucid dreams and self-ratings of dreams. Several methodological considerations may have played a role in the negative findings, such as recruitment criteria, the eyes-closed practice signal and the indirect effects of tAC stimulation during the phosphene and sensation tests. The latter may have masked a real, albeit weak, tAC stimulation effect. Thus, many subjects were able to signal or report lucid dreams in this study, and this supports the notion that further study of lucid dreaming may lead to fruitful applications. Investigating lucid dreaming could be useful for increasing our knowledge of the physiological substrate of dreams, for clarifying theories of consciousness, and for developing potential clinical tools.

This thesis begins with a philosophical question: What if we could amplify our waking experience with the aesthetic qualitiesof dreams? Through a discourse on experiential dream related aspects in philosophy, design and daily life it examines what itmeans, and has meant, to dream, and how these qualities already permeate the physical world. I hypothesize that objects capable of representing dream related physiological data as physical output have the potential to amplify our waking experience. To formulate a set of considerations for the design of such objects, an ethnographic study of dream experience, comprising a survey, a cultural probe study and interviews, has been conducted. The text concludes by exploring how dream elements like ambiguity, synesthetic sensibility, and affective self-exploration may benefit interaction design, raising questions about how digital media can facilitate personal, meaningful experiences.

In this dissertation, disability theories frame readings of madness in select works by Shirley Jackson, Sylvia Plath, and Toni Cade Bambara. The dissertation explores the relationship between madness and fiction, with the author demonstrating the productive and generative aspects of madness. Close readings of the literary works emphasize the impact of madness on structural and formal elements including narrative perspective, sustained metaphors, and narrative time. In chapter one, I use the disability theory concepts of narrative prosthesis and aesthetic nervousness to read Jackson's The Haunting of Hill House. In chapter 2, I analyze Jackson's We Have Always Lived in the Castle to explore the concept of unreliable narration, observing similarities between the social model of disability and reader-centric theories of unreliable narration. In chapter 3, I explore unhealthy disability and medical treatment in the sustained metaphors of light and darkness in Plath's hospital stories, "Tongues of Stone," "Johnny Panic and the Bible of Dreams," and "The Daughters of Blossom Street." In chapter 4, I use disability history to read narratives of medical institutionalization in Plath's novel The Bell Jar. In chapter 5, I use Bambara's concept of "other kinds of intelligences" to develop a Black feminist methodology for reading mad intelligences in Bambara's novel The Salt Eaters. In the dissertation's conclusion, I note prejudice against madpersons in recent legal policies promoting involuntary psychiatric institutionalization, using Bambara's short story "The Hammer Man" to demonstrate the violence of such policies.

While the strategy of lending a voice to the monstrous is a well known aspect of Howard Phillips Lovecraft's works, the female monster is a notable exception to this case. In this thesis, I excavate a theory of female monstrosity through a reading of some of Lovecraft's most read stories and the agency of female characters that appears within. Comparing these female registers of monstrosity to their masculine counterpart, I develop a concept of female monstrosity manifested through categories of class, race and gender with the help of Judith Halberstams theories of monstrosity. Rather than treating these women as active characters, I argue that Lovecraft's inability to handle these monsters forces him to literally put them away – in attics, cellars, or boxes. These are the marginalized positions from which these women elaborate a monstrous form that transcends the boundaries of sex, gender, class and race. Here lurks a female monster, powerful, independent and evil, Lovecraft's treatment of which reveals his fear of its unfettered emergence. Thus Lovecraft’s narrative technique is broken by his own creation. Indeed, these women, in their reproductive capabilities and the monstrous motherhood they represent, are the true monsters of the Lovecraftian universe.

The works of Werner Herzog run parallel with fundamental anthropology, which seeks to understand the process of penetration of man into the world and the inseparable process of penetration of the world into man. The first movie that is analyzed, Wodaabe: Herdsman of the Sun, deals with love of beauty among beings who feel despised by neighboring peoples. The second, Grizzly Man, is about a man who wanted to be a bear, as he could not stand living among humans. The third, The Cave of Forgotten Dreams, tells us how humankind dreamed 32 thousand years ago; how it projected its double on cave walls and small statues. Paintings and statues feature at the same time a penchant for both the fantastic and the reality of shapes and forms. It is not Herzog´s movie settings or themes which are anthropological; it is his view of the world and his way of making movies, which transmutes real into imaginary, and imaginary into real / Todo cinema contém um caráter antropológico, por ser aberto como a própria humanidade. A obra de Werner Herzog é contigua à antropologia fundamental, que busca compreender o processo de penetração do homem no mundo e o processo inseparável de penetração do mundo no homem. O primeiro filme analisado, Wodaabe: Os pastores do sol, trata do amor à beleza entre seres que se sentem desprezados pelos povos vizinhos. O segundo, O homem urso, de um humano que queria ser urso e não suportava o mundo dos humanos. O terceiro, A caverna dos sonhos esquecidos, conta como sonhava a humanidade há 32 mil anos, como projetava seu duplo nas paredes das cavernas e nas pequenas estátuas. Nas pinturas e estátuas estão presentes, ao mesmo tempo, uma tendência para o fantástico e para a realidade das formas. Não são os locais de filmagem e tampouco os temas de Herzog que são antropológicos, mas sim a sua visão de mundo e o modo de fazer cinema, que transmuta o real em imaginário e o imaginário em real
