Debunking the popular myth that "A dream is not that which you see while sleeping; it is something that does not let you sleep"!
Dreams (and sleep) are the keys to success !!
It is during rapid eye movement(REM sleep), that your brain assimilates and indexes information in your long-term memory, just like disc-defragmenter and disc-cleaner processes run in the background of your operating system during idle-time, when the processors are reasonably idle. Sleep is a crucial time for cognitive consolidation, in which synaptic changes associated with recently stored memories become durable and stable. As your brain runs the de-fragmenter and re-organizer, it obviously has to load the intermediate nodes into working memory. It is during these periods that vivid dreams are most likely to occur.
Sleep confers many physical and cognitive benefits, and yet many of us don’t get enough of it. Indeed, many candidates indicate that they have recently pulled an “all-nighter” during which they didn’t sleep at all. When we do not get enough sleep, our bodies operate abnormally; indeed, sleep loss can adversely affect many different systems in our body, including our brain, hormones, and immune system.
Whatever nodes of knowledge have been newly acquired in memory cannot be efficiently shifted around and integrated with existing and organized pieces of knowledge, thereby impairing later retrieval and wisdom, in general. Sleep is also necessary for normal mental functioning. Chronic sleep deprivation increases levels of the stress hormone cortisol, which may damage or impair brain cells that are necessary for learning and memory. Also, new brain cells may either fail to develop or may mature abnormally. Perhaps in part because of such damage, after the loss of even a single night’s sleep, mental flexibility, attention, mood, and creativity all suffer. After several days straight of staying awake, people may even begin to have hallucinations and delusions.
Thus, dreams are an unavoidable and natural corollary of normal sleep and growth, both physical as well as cognitive!
