"falsified" reality

i wonder, if cant look through your eyes than how do i know your real, i've had dreams as vivid as life, is this all life a figment of our own creativity, imagine then what "real" life would be then, would we be by ourselves, would we be ourselves, would we see anyone from our dream world in the real world. think of the former, alone in what would seem a foriegn enviroment yet be our home, see our parents, scared of their strangeness, would you eat their food , would they speak our langauge. a enviroment totally alien yet....................... home.
