In this article Linden explains one leading neurobiological theory of dreaming, that dreams help us deal with emotions by encoding and constructing memories of them. Essentially dreamings purpose is to relive a memory in our dream but strip the emotion out of the experience, so when we recall the memory while awake we are not taxed by the emotional toll of the experience. This process satisfies an important role because when we don’t process our grief, it escalates feelings of restlessness and anxiety. In a recent study by the Sleep and Neuroimaging Lab at UC Berkeley results showed “participants who exhibited more low frequency theta waves in the frontal lobes were more likely to remember their dreams.” These findings are important because the increased frontal lobe activity looks just like encoding and retrieval of memories. Therefore, this study shows that the neurophysiological mechanisms that we use while dreaming are the same as when we create and retrieve memories while we are awake.
