that suggest analogous existance of more important, psychical pressure on sleeper: an internal stimulus. This internal stimulation emerges either because of the continuation of our diurnal mental activity or pressure of our unsatisfied instinctive aspirations. The latter are in psychotherapy very important, because they can express those conflicts, which are the cause for mental disease. The possibility that such disturbance occures during the sleep lies in relation between conscious ego and unconscious id1. Suppressed aspirations of id do not conform to ego's desire to sleep and thus gain certain independancy. These unsatisfied aspirations fight their way through conscious ego in a dream, which is unlikely to happen during the day. The dreams are therefore above all psychological and not somatic phenomenon. If it was that simple, we would be able to reveal the meaning of dreams with ease. In truth, this process is much more complicated. Conscious ego never gives up completely. Under the influence of superego, it transforms and hides id's aspirations, because the task of dream is to maintain sleep and protect the sleeper from being disturbed. The effort to hide inadmissible instinctive aspirations forms manifest and latent content of dream. 2.1.2 Manifest and latent contentThe manifest content of dream is the content which the dreamer remembers and relates. Behind this content there is usually hidden the latent content of dream as "the dream we remember [sic] is not exactly the right thing, but rather a deformed substitute for dream." (Freud 1977: 116) I say usually, because we also know dreams in which latent content matches with manifest content. Such kind of dreams are often experienced by little children as a result of not yet developed ego and superego, which would transform unsatisfied instinctive aspirations. However, this type of dreams occur to grown-ups in certain circumstances as well and Freud called them infantile dreams. ...
