Yeah so, dreams are weird. I wake myself up when I talk in my sleep. I woke up the other morning mumbling something along the lines of

"and now with this we'll be able to finally cure cancer.... huh?"

The world can't have that cure because daylight decided it was much more important to wake me up so I could take the garbage out. What feats of humanity are lost to the sea of slumber my friends? What insights are sold to the sand man while the world rests? Ask not, for "a great many" may be the answer you find. Then again "Not really very many" may be the answer you may find... Perhaps "erm none... they're all rubbish" might manifest as the solution to this eternal riddle. One may never know (but one could totally guess)
