Freud believed that dreams have a meaning which can be interpreted through the use of symbolic relationships. Dreams can be divided into three categories in relation to their manifest and latent content. The first category is dreams that are intelligible and that can be easily related to one’s mental life. The second category is dreams which, although sensible and clear, have a confusing effect because they do not fit with our mental life. And the third category is dreams that are incoherent, disconnected and seemingly meaningless. It is the second and third categories which are significant concerning the manifest and latent content of dreams. The manifest content of a dream is the fragmentary and illogical story that it tells. The latent content of a dream is concerned with the ‘dream thoughts’ that occur within this dream story. Freud asserts that, on analysis, the manifest content of a dream deals with material that is quite different to the latent thoughts. The distinction between the two contents show that the essential content of a dream is obscured, playing a subordinate role and the most latent content is not even present or is only remotely alluded to it. The more obscure the dream, the more displacement has occurred.
