6、)，这一时期大脑活动活跃。某些科学家认为深睡期睡眠能让身体休息，保存精力，就像动物冬眠一样。Ones life will take 1/4 of the time to sleep.However,the fundamental reason is still sleeping like a powerful and unconstrained style dreams like people very much puzzled.Long term insomnia can lead to trance,hallucinations,and ultimately cause death.Sle

8、ucination是一种虚幻的表象，本来并不存在的某种事物，病人却感知它的存在。正常人偶尔也可出现幻觉，比如在焦虑地等待某人到来时，忽然听到敲门声，实际却没有人来。这种幻听的出现与期待的心理有密切关系，此外在受到突然强烈的刺激下亦可出现幻觉。正常人在殷切盼望、强烈期待、高度紧张情绪影响下，也可出现某种片断而瞬逝的幻觉，如一个母亲突然失去儿子，悲痛万分，有时幻听到儿子在同她讲话等等。这种幻觉往往持续时间不会太长，随着心情的好转，适当的治疗，便会痊愈。Is a kind of illusory image,there is no one thing,the patient is aware of

11、d.幻觉具有两个主要特点：第一、幻觉是一种感受，由于缺乏相应的现实刺激，所以客观检验结果证明这种感受是虚幻的，但就患者自身体验而言，却并不感到虚幻。第二，虽然幻觉源于主观体验，没有客观现实根源，但某些患者坚信其感受来自客观现实。The illusion has two main characteristics:first,the illusion is a kind of feeling,because of the lack of the corresponding real stimulation,so the objective test results prove that this

12、feeling is illusory,but the patients own experience,but did not feel unreal.Second,although the illusion is derived from the subjective experience,there is no objective reality,but some patients believe that their feelings from the objective reality.幻觉可分为真性幻觉、假性幻觉和残留性幻觉三类。真性幻觉时，大脑皮层感受区的自发性兴奋使以往映象活跃化

13、而重现出来，此即表象。由于表象特别强烈，鲜明、生动、详尽而投射到外部客观世界。投射是指当表象活化的强度大到与现实刺激产生映象的同样程度时，在人的意识中就无法与现实刺激映象相区别，而是按照生活惯例习以为常地认为它是来自客观空间，所以这是一种自然而然的向外投射过程。Can be divided into true hallucination,illusion and hallucination pseudohallucination residue three.True hallucination,the cerebral cortex excitatory spontaneous feeling
