this episode be a bit confuse . some people say that you have to start from the very begin but i have to say i be a bit confused from the beginning . clark get a blow to the head and wake up on the floor of fairview mental institution and be make fun of for believe that he a superhero . clark be tell that the life that he know be all in his head . delusional . he also find some thing that be unusual represent martha marry to lionel while lex be bind to a wheelchair with his limb cut off after his accident on the bridge while and lana be devote to clark . but he find one familiarity while someone else who devote to clark represent chloe . he also find that a mental patient be also from the know world of smallville . and the doctor be an escapee from the phantom zone . this episode remind me right back to a buffy episode call normal again where buffy begin to have vivid daydream about a mental asylum . the doctor try to convince her that all that she know be a figment of her imagination and that she be and in fact and crazy . her parent be still marry and they still live in la and her friend do not exist and angel be never her boyfriend and she do not have a sister call dawn . demon and vampire also do not exist . both episode be a bit sad because doctor aren not just tell the character that it all a figment of her imagination but it tell u what it really be represent fiction and and it bring u back to reality . it nice and though and to have a sense of reality every once in a while and but we watch these show to escape from reality . it again nice because the character have to overcome new challenge .
