Totem spin in Mombasa
I'm sure this has been discussed countless times, but did anyone else notice that when Cobb awoken to Yusuf's dream compound in Mombasa, his totem never really fell over(as he was interrupted by Saito), thus never fully assuring the audience that he ever awoke from his dream state? Is it possible this entire mission was simply carried out in one of the many layers of Cobb's subconscious while asleep in Mombassa?
