    Can we be “out” of our body? Characterization and clinical implications of out-of-body experiences during sleep paralysis: Preliminary results
    (2021) Herrero, Nerea; Gallo, Francisco; Forcato, Cecilia
    "Sleep paralysis is a period of transitory immobility which occurs during sleep onset or offset. It is characterized by the inability to perform voluntary movements when the person feels awake and conscious about the environment. During an episode of sleep paralysis can occur different types of hallucinations: The Intruder, characterized by the sense of an evil and threatening presence, visual and tactile hallucinations. The Incubus, characterized pressure on the chest and other body parts, breathing difficulties, feelings of suffocation, choking, pain and morbid thoughts of imminent death. Unusual body experiences which includes Illusory Movement Experiences (IMEs) and Out of Body Experiences (OBEs). IMEs are vestibular sensations such as the sensation of rolling or floating, and/or motor sensations of displacement without a visual component.The OBEs are an altered state of consciousness, defined as the experience in which an observer perceives the world from a point of view outside of their physical body. Unlike the other two components (incubus and intruder), during IMEs and OBEs the person may not feel body paralysis, and they are considered as more pleasant. OBEs during sleep paralysis can occur spontaneously or it can be induced with training by the recognition of an aura that precedes the experience. Here, we will discuss preliminary results of an online survey with subjects who had unusual sleep experiences, such as OBEs and Sleep Paralysis and its clinical implications."

    Out of body experience during sleep paralysis: an altered state of consciousness. Preliminary results
    (2020) Herrero, Nerea; Gallo, Francisco; Gleiser, Pablo; Forcato, Cecilia
    "We understand consciousness as the subjective experience the "How is it..." to perceive a scene, recognize a face, hear a sound, or reflect on the experience itself. It can be considered a dynamic process and it can be temporarily divided into states. The states of consciousness depend one’s subjective experience and8 it’s associated neurobiological correlates, and they can be divided in physiological, pathological or altered states. The Out of Body Experiences (OBEs) are an altered state of consciousness, defined as the experience in which an observer perceives the world from a point of view outside of their physical body. OBEs reflect an alteration in the multisensory association cortexes, with the parieto-temporal junction (TPJ) playing a fundamental role. These experiences can occur during sleep paralysis. Sleep paralysis is caused by an intrusion of Rapid Eye Movement sleep (REM) into wakefulness. It is a state which can occur when waking up or falling asleep, in which a person is aware but unable to move or speak. It can be accompanied by a sense of a presence, auditory and visual hallucinations and in some cases OBEs. OBEs during sleep paralysis can occur spontaneously, or they can be induced by training. Here, we conducted an interview with subjects who had spontaneous OBE during sleep paralysis (S-OBE) and subjects who apply techniques to induce it (I-OBEs)."

    Spontaneous and induced out-of-body experiences during sleep paralysis: Emotions, “AURA” recognition, and clinical implications
    (2022) Herrero, Nerea; Gallo, Francisco; Gasca-Rolín, Miguel; Gleiser, Pablo M.; Forcato, Cecilia
    "Sleep paralysis is characterized by the incapacity to perform voluntary movements during sleep/wake transitions, and could bring great discomfort. During sleep paraly sis, out-of-body experiences can occur. Out-of-body experiences refers to the sensation of being outside of the physical body and perceiving the world from this outside perspective; however, they are pleasant in comparison with other sleep paralysis hallucinations. Lucid dreams are dreams in which a subject becomes aware of being dreaming while the dream occurs. Here, we designed an online survey to study the predominant and specific emotions during sleep paralysis and/or out-of-body experience events as well as the somatosensory perceptions that preceded their occurrence. The sample (N = 329) was divided into experimental groups depending on the presence/absence of out-of-body experiences, capacity to induce (or not) out-of body experiences, and perception/no-perception of the sleep paralysis. We showed that more positive emotions were associated with out-of-body experiences and more negative emotions were associated with sleep paralysis episodes, and for those who claim the ability to induce out-of-body experiences, positive emotions were more frequent in their episodes. We found that subjects perceived auditory, tactile and visual sensations before sleep paralysis episodes, and we proposed that these could be an “aura” of sleep paralysis. Furthermore, subjects that had out-of-body experiences but had never felt the sleep paralysis, perceived tactile and visual sensations to the same extent as subjects with out-of-body experiences that felt the sleep paralysis." Therefore, we proposed that the “aura” recognition could be used under controlled conditions for out-of-body experiences induction in patients with sleep paralysis to diminish the negative symptoms associated with sleep paralysis episodes
