Watched 2nd time, the totem wobbles in the end, and looses spinning power. So it might be real. But as someone said earlier, the kids dont age. 1 more thing, in the beginning, we can hear a women's voice, but in the end the voice is nowhere to be heard??? As a father wasnt it odd if he doesnt know his kid's face???

another thing i dont quite understand. The kick is actually the fall. When they demo the kick/fall, when arthur fall during sleep mood, he will wake up, so its like if I fall in this level, the "me" in 1 level below will dissapear. This explains a lot, but not the last level, when fisher and ariardne fall off the building. Shouldnt it be at the level above them??? Or its the demo that has gone wrong???

On 2 occasion Cobb didnt manage to spin the totem, one is the toilet part, the other 1 is when he and ariardne visits his prison of memory.
