On seeing the Above scan link ^ A couple of things came to mind:
1) The moon - Indicated Mugen Tsukyomi
2) The Way the Tree's spiraled toward it - Indicated Tobi's Mask
3) The sudden Change in Time and Location - Tsukyomi/izanagi.
From the moment Obito began seeing things through his Blind eye, in lego form...i figured he was under Madara's Genjutsu.
Madara wasn't hibernating, as many thought...and Obito was there for a while. I guess Madara also observed his constant "Rin and Kakashi" calls, and decided to use them to manipulate him.
Maybe Madara through zetsu, saw the entire Fight and used that memory in a genjutsu on Obito, To Manipulate him into the current psyco that he is.
