When he was in the bathroom after meeting that chemist guy or whatever and he splashes his face and then spins the top.. Does he knock the top over onto the floor and it kept spinning? Or did it fall over on it's own? My brother says that he knocked it over because he was startled and that it kept spinning on the floor or whatever when that asian guy came in.

I'm pretty sure it fell over.......... but I don't remember the scene.

My brother is convinced it was all a dream.

I guess it depends on whether you believe the totem works or not. I don't remember that specific scene above but there were definitely scenes where the top fell over.

I think the totems do work~ And Yes.. there were scenes when it fell. He is going back and forth now. He says there were scenes when the totem fell but it was still all a dream. /NOSENSE

Or that last scene with the top wobbling was an inception as well!!!!

But UGH!! I hate all these theories that involve Cobb's father and some theories that involve Cobb's MOTHER as well... ~_~;;
