REM Stage :- The sleep stage where we start dreaming is called Rapid Eye Movement(REM). Dreaming occurs most often and intensely during the REM sleep. REM is when the brain’s neuroelectrical systems rise to peak levels as high as levels found in waking consciousness.
However, dreaming can also occur outside of REM sleep. REM sleep is neither necessary nor sufficient for dreaming.
REM sleep helps in the growth and development of the brain in the newborns. Newborn spend up-to 80 % of their sleep in the REM phase which leads to neutral maturation and psychological development. The brain experiences intense visionary imagery while dreaming during which it shifts into a different mode of regional activation. Areas focused on attention and rational thinking become less active while areas involved with emotions and visual imagination become more active which can generate some intense visionary experiences.

It begins in the middle of a dream when you realize that the experience is not occurring in physical reality.
