Melatonin is a hormone that is naturally produced in the brain and then is released directly into our bloodstream. Brain basics: A guide to dreaming at night Melatonin Here is an extensive article to help you know everything about NREM in depth. Each stage lasts for different time durations throughout the night. Non-REM, also known as NREM, has various subsequent sleep stages. In young kids, about 50% of the sleep time constitutes REM sleep, whereas adults experience only 20% of deep sleep. As you grow older, the deep sleep stage starts to decrease in terms of time and intensity in most people. It is likely to have intense dreams during this sleeping stage as the brain functions actively at that moment. This is the deepest stage of sleeping that happens about 90 minutes after you have closed your eyes to sleep.

They can happen anytime during sleep, but the most vivid dreams occur during the phase called REM sleep (rapid eye movement sleep) when one's brain is most active. Dreams are mostly the result of our thoughts and impulses that we repress during the waking hours of the day. It is very common to have around four to seven dreams in one night. Statistically, we spend over one-third of our life sleeping, and on average, we spend a total of about six years dreaming. Dreams have been a huge part of our lives for as long as we have existed.
