關(guān)于夢境的學說很多的說，目前所有的理論大概有以下幾個學派：During the night there may be many external stimuli bombarding the senses, but the mind interprets the stimulus and makes it a part of a dream in order to ensure continued sleep. The mind will, however, awaken an individual if they are in danger or if trained to respond to certain sounds, such as a baby allow the repressed parts of the mind to be satisfied through fantasy while keeping the conscious mind from thoughts that would suddenly cause one to awaken from suggested that bad dreams let the brain learn to gain control over emotions resulting from distressing suggested that dreams may compensate for one-sided attitudes held in waking proposed that the dream, when told, may communicate something that is not being said are like the cleaning-up operations of computers when they are off-line, removing parasitic nodes and other "junk" from the mind during create new ideas through the generation of random thought mutations. Some of these may be rejected by the mind as useless, while others may be seen as valuable and retained. Blechner calls this the theory of "Oneiric Darwinism."Dreams regulate says dreams may function like psychotherapy, by "making connections in a safe place" and allowing the dreamer to integrate thoughts that may be dissociated during waking recent research by Griffin has led to the formulation of the 'expectation fulfillment theory of dreaming', which suggests that dreaming metaphorically completes patterns of emotional expectation and lowers stress hypothesizes that dreams modify and test mental schemas during sleep during a process he calls emotional selection, and that only schema modifications that appear emotionally adaptive during dream tests are selected for retention, while those that appear maladaptive are abandoned or further modified and are a product of dissociated imagination, which is dissociated from the conscious self and draws material from sensory memory for simulation, with sensory feedback resulting in hallucination. By simulating the sensory signals to drive the autonomous nerves, dreams can effect mind-body interaction. In the brain and spine, the autonomous "repair nerves", which can expand the blood vessels, connect with pain and compression nerves. These nerves are grouped into many chains called meridians in Chinese medicine. While dreaming, the body also employs the chain-reacting meridians to repair the body and help it grow and develop by sending out very intensive movement-compression signals when the level of growth enzymes increase. 如果是夢游殺人那就不知道啦，沒有研究過，但是有夢游殺人的先例就是啦。 國內(nèi)比較出名的就是新疆喀什地區(qū)莎車縣的一個案件。真實性不確定。。另外大腦受損這個說法有點牽強啦雖然有可能，但是目前是沒有這個理論的另外國內(nèi)的心理醫(yī)生大部分都說沒有什么用的找個厲害一點的試一下催眠，看看能不能在樓主男朋友的潛意識里發(fā)現(xiàn)些什么。如果還是不行的話，不如叫男友嘗試一下下次做夢留意一下夢里的藏尸地點，然后去那里挖挖看 －____-
