Comparing Lucid and Non-Lucid Dream Content. Some scientists seem to assume that lucid dreams are “too different” from non-lucid dreams to use lucid dreamers to study, for example, mind-body relationships during REM sleep. With an aim towards understanding the extent to which lucid dreams differ from non-lucid dreams in other ways than (obviously) whether or not the dreamer knows it is a dream at the time, we have designed the following simple study. In short, we are asking for four dream reports via email; Two of these reports should be lucid dreams, and two should be non-lucid dreams.
Modern popular culture often conceives of dreams, like Freud, as expressions of the dreamer's deepest fears and desires.  The film version of The Wizard of Oz (1939) depicts a full-color dream that causes Dorothy to perceive her black-and-white reality and those with whom she shares it in a new way. In films such as Spellbound (1945), The Manchurian Candidate (1962), Field of Dreams (1989), and Inception (2010), the protagonists must extract vital clues from surreal dreams.
