PET and fMRI scans were taken to reveal the dreams developing. Areas showed colors defining where the dreams are occurring such as the limbic system related to motivation, emotion, and memory. Areas include the hippocampus and the amygdala. Patients who were not able to recall dreams were compared to patients who haven’t been able to recall dreams for 10 years. Rapid eye movement was proof the patients were dreaming, but not capable of recalling the dream (Herlin, et al, 2015). Studies show to complete the correct sleeping cycle, REM sleep must be achieved. Nights may show that REM sleep was not reached but the body was not fully rested. Bodies who are not fully reaching REM sleep cannot have the ability to dream, which is correct, but when REM sleep in reached, dreams are being developed. Not all dreams can be recalled, making the brain believe no dreams are being developed which is a myth. Sleep has a main function of helping improve memory formation. Explained, the theory by Sigmund Freud, dreams can have a symbolic meaning even when not recalled. Dreams most commonly reflect on interests called neurocognitive theory. Non-dreamers are mistaken with sleep disorders which is not the case, the brain doesn’t have the ability to …show more content…
Chapter 4 begins the discussion sleep and dreams. Studies include the use of electroencephalograms (EEG) which monitors the brain activity during sleep. This process can detect the difference between NREM and REM. NREM, non-rapid eye movement sleep, also called quiet sleep, is the process where hallucinations occur. Examples include, the sensation of falling, body spasms, and being the center of a recently watched movie or video game. NREM has 4 stages of sleep which occur the first 50-70 minutes of the sleep and REM occurs immediately after around the 90 minute mark (Hockenbury, Nolan & Hockenbury 2016). Stages of NREM are determined by the decrease in the body and brain activity. During stage one, vivid imagery is not common, but most commonly in stage 4 or the beginning of REM. REM sleep has more brain activity producing smaller brain waves meaning waves are at a faster pace. NREM and REM sleep begin to cycle back and forth throughout the night with 90 minutes
