don't knock it till you've tried it. it is easy (in relative terms) to establish its existance but a lot harder to prove its non-existance.

it would be a great way to get lucid though, eh? you're walking around some odd place thinking "this is normal and i am just living my waking life. la de da"

then this guy runs over and says "hey, i'm super duck from dv and you're dreaming. get lucid now!"

wham! you're lucid and you love me for it. two birds with one stone, me thinks. hehe.
