...Scientist who measure Dreams ..through various Physical instruments ...are probably looking at the wrong side... though it too gives clues ...
...but during dreaming ...though a man is physically in this world...but ..some where in the mind it opens door ...a door where probably .. he gets out of the box....and see thing in their actuality ...now with no restriction or restrain on the laws following time-Space laws...he often sees the future as well as past or some other dimension or existence .....
...but then he is not physically present there...and his normal 5 senses are probably not working ...so the information that his mind now gets from Other senses ...which somehow get invoked or start working albeit temporarily ... his mind infers the perceptions according to the physical program of his mind... his mind is not programed to understand all the new realities he sees or experiences now... ..then there is return back journey .. during which he has close too many doors.. and with each door or perception closed again...he begins to forget.. and when he wakes up...
...all that remains is a ' Reshimo " ...a lingering remembrance of what he saw... and often again wrapped behind the closed doors...
...as again all those senses of perception became in operative...his minds fails to understand them .. " the chip loses electricity ...and all the info remains is just a distorted memory .."
