Sigmund Freud's thesis was that there is a censorship during waking that prevents memory of events, drives, wishes, and feelings from entering the consciousness because they would induce anxiety due to their emotional or ethical unacceptability. During dreaming, because the efficiency of censorship is decreased, latent thought contents can, after dream-work involving condensation and displacement, enter the dreamer's consciousness under the figurative form of manifest content. The quasi-closed dogma of psychoanalytic theory as related to unconscious processes is beginning to find neurobiological confirmation during waking. Indeed, there are active processes that suppress (repress) unwanted memories from entering consciousness. In contrast, it is more difficult to find neurobiological evidence supporting an organized dream-work that would induce meaningful symbolic content, since dream mentation most often only shows psychotic-like activities.
西格蒙德·弗洛伊德的论点是，在清醒状态下存在一种审查机制，防止记忆、驱力、愿望和情感进入意识，因为它们会因其情感或道德上的不可接受性而引起焦虑。在做梦时，由于审查机制的效率降低，潜在的思维内容可以在经过涉及凝缩和置换的梦的工作后，以显梦内容的象征性形式进入做梦者的意识。与无意识过程相关的精神分析理论的准封闭教条开始在清醒状态下找到神经生物学的证实。事实上，存在着积极的过程来抑制（压抑）不想要的记忆进入意识。相比之下，要找到支持有组织的梦的工作的神经生物学证据则更为困难，因为梦的思维通常只表现出类似精神病的活动。
