During sleep we see a lot of events and we go to different places, the explanation of this on our current reality? And whether these things can happen or happened.
Dreams are basically stories and images our mind creates while we sleep. Dreams can be vivid. They can make you feel happy, sad, or scared. And they may seem confusing or perfectly rational.
Dreams can occur anytime during sleep. But most vivid dreams occur during deep, REM (rapid eye movement) sleep, when the brain is most active. Some experts say we dream at least four to six times per night.
Being a dream researcher for me, Dream is an epiphenomenon state and it is real like waking. I do not want to consider this state as unreal rather I would say 'a differently real state'.
