On the whole, relating typical dreams to the neurophysiology of REM sleep has proven to be a useful starting point for revealing the neural basis of dreaming. However, dream consciousness can not be reduced to brain activity in REM sleep. Indeed, some fundamental questions concerning the relationship between the brain and dreaming linger on.

Even with recent scientific investigations of dreaming, our dreams still remain something of a mystery. Some experts suggest that dreams represent the replay of the day’s events as a critical mechanism in the formation of memories, while others claim that the content of dreams is simply the result of random activity in the brain.
Dreaming is therefore merely an incidental result of the brain’s need for continual activation. But whatever the underlying reasons for why dreams arise, the physiological and neurological mechanisms underpinning the act of dreaming are, while still not entirely understood, gradually beginning to become clearer as modern research progresses.
But to truly understand what goes on in the brain while you sleep and dream, it’s useful to examine each step. Stage 1. At this stage, sleep is very light and can easily be disrupted. Mental activity begins to slow down, with brain waves switching to a form called theta-band activity.
Lucid dreaming is a very interesting phenomenon that perhaps gives us a peek into the inner workings of the human brain. I have had about a dozen lucid dreams in my life that I can remember. Normally while dreaming we are not aware of the fact that we are dreaming. Our dreaming selves accept the reality of the dream. During a lucid dream we become aware that we are dreaming, but we do not wake up.
Why Your Brain Needs to Dream ... while many of us may feel that our dreams have special meaning or a useful purpose, science has been more skeptical of that claim. ... and we found that specific brain activity that reflected a drop in stress-related brain chemistry during the dream state determined the success of overnight therapy from one ...
Brain/Body Activity During Sleep and Dreams There are three majors measures of sleep that are used in the sleep laboratory; brain waves, eye movements and muscle tone. In Figure 1 waking is compared to the two basic categories of sleep: NREM and REM sleep.
