Why Do We Dream?

"Since the record's history began, dreams and subsequent emotional interpretations have been studied and recorded" (as quoted by Palagini; Rodenlicht, 2010). Recent experimental studies of neurobiological and psychological aspects applied to sleep have identified a large dynamic arousal state which in turn predicts various physiological responses. One of the important stages of association during sleep is called REM (rapid eye movement) sleep, and REM sleep is considered to be the main dream period at a certain stage.

The suggested question "Why are we dreaming?" Is easier to ask but a more difficult question to explain. At the moment, we have some ignorance about sleep and dreams based on the fact that we do not yet understand the function of dreams. Despite some theories about the concept of dreams, there is an important understanding of the purpose of sleep or the function of REM sleep. Recent theories and opinions about dreams give us the impression that dreams do not have any biological function in cognitive neuroscience. Neurophysiological events associated with REM sleep and dreams have biological function as they support functions that help restore brain development and neurochemical balance of the brain.

The problem is "Why should we have a dream?" Or "What is the function to dream?" It's easy to ask, but it is difficult to answer. The most honest answer is that we do not yet know the function or function of a dream. Despite the many theories we do not fully understand the purpose of sleep yet this ignorance is not surprising. And these two biological states are easier to study scientifically than somewhat obscure ones.
