An important procedure for obtaining data on the unconscious and subconscious occurs through dream analysis (Butcher, 2013). During sleep a person's mental defensive filters lower. Therefore, forbidden desires such as sex and emotional feelings of repression can be found in the client's dream. The mind interprets this unconscious cognition and masks these feelings in the form of symbolism. (2013) This is why dream interpretation is a valid form of gathering information about an individual's subconscious and emotional stressors. Dreams contain two types of content, the manifest content which is the dream as it appears and the latent content which contains the dreamer's real motivations which are repressed into symbols because they are unacceptable or painful ruminations (2013). The psychologist must associate these symbols with meanings using the client and the correlation between the client and the meanings. For example, a client may have a recurring dream of dying, this could mean they are afraid of death. In many cases, dreams are believed to be mental disorders. Dream analysis is a highly underrated information gathering method that has yet to be used to its full potential. Vivid, violent dreams can predict half a century's worth of brain disorders. (Sanders, 2010) REM sleep behavior disorder, or RBD, may be comorbid with neurodegenerative diseases that include Parkinson's and Lewy body dementia (Sanders, 2010) People with RBD dreams tend to have higher reports of violence and often include struggling with a seizure or experiencing death. Symptoms of RBD include restlessness and often dreams with screaming and punching, as if they were actually experiencing the dream. These symptoms can be detected in ... middle of paper ......presses but also repressed desires and possible predetermination of some psychological disorders. Using dream material is also a good way to change the way we look at and define ourselves; and therefore to help patients find a new understanding of themselves, new ways of behaving, new aspects of personality (Calmar, 1987). Dreams about drugs could represent some data about addiction and the relationship with craving and withdrawal. Dreams that include the patient's drug of choice during sobriety are the biological manifestation of addiction and can be used in therapy to allow the patient to realize the addiction and the need to relapse. Nightmares are even more common among recovering alcoholics and are thought to be traumatic and serious. Nightmares are common in the drug-addicted population due to a higher incidence of childhood abuse and post-traumatic stress disorder (Johnson, 2012).
