    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)."
