According to my own thinking...... Human dreams originates in the CNS but they don't depends only upon CNS..... CNS only start the dreams and PNS continue the dream...... You can say if you are sleeping in your dream then the dream only maintained by the CNS haha its amazing to sleep in your dream.... But your dream is motile then CNS and PNS both required... Actually while you dreaming the PNS sends the weak signals to the brain... Then you think why we don't move our body while dreaming..... It may be that signals by nerves of low voltage and 100 of times weak than normal.... Actually believe it or not but I think and believe we also feel reflex action in the dreams... A weak reflex action of low voltage.. According to my own, dreams aren't 3D videos but they are sequence of the 3D images i can say this from the dreams not controlled by concious mind but they are controlled by subconscious and unconscious mind...... The unconscious mind don't have enough power to switch video mode in our brain so.... Ok it may look little strange to you that dream aren't videos bt it may true if Im true.... Actually we forget our most of dreams so we can't say confidently that dreams are videos or sequential images....Ok maine aisa kha aisa ho sakta hai If my thinking is right
