Abstract：
The Doppelgänger phenomenon refers to the experience of a direct encounter with one\'s self, characteriswed by: (i) the perception of a figure with one\'s own identical physical features; or (ii) the apprehension that the perceived figure shares the same personality and identity. The Doppelgänger does not only look like the same person, it is his/her double. The perceptual element is usually a hallucination, although occasionally a false perception of an actual figure may be involved. This phenomenon has been described in individuals suffering from overwhelming fear, severe anxiety or intoxication, epilepsy, as well as in the sleep-wakefulness transition. It has also been reported in major psychoses. The fear of imminent death often precedes the Doppelgänger experience. This report presents the case of a 30-year-old man, Mr. Y, who was stabbed to death by Mr. X, his \"double\". The aggressor and his victim, although not related, were truly doubles; remarkably, they shared the same name and surname, age, professional activity and place of work. Moreover, they attended the same sports center but barely knew each other. The forensic psychiatric evaluations in Mr. X, subsequent to the crime committed, were suggestive of a psychotic condition. This case is unique in the scientific literature. In the most serious psychotic forms, the issue of the \"double\" calls into question not only the dissociative processes involved in the etiopathogenesis of the disorder, but also bio-psycho-social elements, as well as personal data in this case, which made the victim and the aggressor \"identical\". In the context of psychopathological functioning, the delusional mood (Wahnstimmung) that precedes the development of delirium is a sort of gateway to an impending psychotic illness, involving delusional awareness or mood (atmosphere). In psychosis, splitting is the main issue and this influence is seen as an evil, foreign, apocalyptic and unknown side no longer recognised as belonging to the self even in a physical sense. In such a situation, it is felt that the only way to survive is by suppressing one\'s double as a defense against disorganisation of the self.
摘要：
Doppelgänger现象是指与自我直接相遇的经验，特征是：（i）对具有自己相同身体特征的人物的感知；或（ii）对感知到的人物具有相同的个性和身份的理解。Doppelgänger不仅看起来像同一个人，这是他/她的两倍。感知元素通常是幻觉，尽管有时可能涉及对实际数字的错误感知。这种现象已经在遭受压倒性恐惧的个体中描述过，严重的焦虑或中毒，癫痫,以及在睡眠-觉醒的过渡中。在主要精神病中也有报道。对即将死亡的恐惧通常先于Doppelgänger的经历。这份报告介绍了一名30岁男子的案例，Y先生,被X先生刺死,他的“双”。侵略者和他的受害者,虽然不相关，是真正的两倍；值得注意的是，他们有相同的名字和姓氏,年龄,专业活动和工作地点。此外，他们参加了同一个体育中心，但彼此几乎不认识。X先生的法医精神病学评估，在犯罪之后，都暗示了精神病.这种情况在科学文献中是独一无二的。在最严重的精神病形式中，“双重”的问题不仅质疑该疾病的病因中涉及的分离过程，还有生物心理社会因素，以及这种情况下的个人数据，这使得受害者和侵略者“完全相同”。在精神病理学功能的背景下，在谵妄发展之前的妄想情绪（Wahnstimung）是一种即将到来的精神病的门户，涉及妄想意识或情绪（气氛）。在精神病中，分裂是主要问题，这种影响被视为邪恶，外国,即使在物理意义上，世界末日和未知的一面也不再被认为属于自我。在这种情况下,人们认为，生存的唯一途径是压制自己的双重防御，以防止自我的混乱。
