at the end of inception the top thingy was still spining, so does that mean that it was in reality or in the the dream???

thats the cliff-hanger. i personly think that they were in the real world because if u noticed at the end the top started to wobble and that never happened in a dream it just kept spinning continuously. no wobbling.

is he still in a dream? well i guess we'll never really know, but here is some evidence that the top would've stopped spinning (thus proving it is reality) had the camera not cut off:

- Cobb has no wedding ring on in the "reality" scenes and he does in the dreams. When he wakes up on the plane and the whole way through immigration he doesnt have a ring on, suggesting he is in reality.

- was the immigration man staring because he was a projection? No, after seeing it twice, it appears to just be the normal scrutiny that officers do at airports

- The totem began to wobble ever so slightly before it cut to black- in a dream it never wobbled, even slightly.

Throughout the film, Cobb continues to obsess about spinning the top and verifying reality – however, at the end of movie, he spins the top and walks away from it before he can verify if it stops spinning or not. His kids come running in and Cobb couldn't care less about about the top or “true reality” or extraction/inception anymore. He just wants to be with his children, in whatever place he can be with them. That emotional connection and desire is “reality” enough for him.

In the end, Cobb walking away from the top is a statement in itself that also completes the arc of his character.
So whether or not its reality, Cobb doesnt care anymore, as long as he is with his children.

That`s the point,everyone decides for themselves. To me,it`s definitely in the reality,but a friend of mine thinks it`s still a dream..

Yea, the ending is left to be interpreted by the audience. I sort of hope he was in reality but I am not sure. But the fact the Cobb walked away before he saw for sure whether the top fell or not showed that he didn't care. Whether he was still dreaming or in reality, he finally got to be reunited with his kids and that's all that mattered to him. ahh I love this movie!

I Personally believe he was present in the real world because if you where paying attention to the movie it stated that Leo would refuse to look at his children s' faces when he was dreaming, but in the end he did therefore he wasn't dreaming. Plus, he resolved the matter with his wife so he could go back to reality with a happier perspective on the things of reality which he did. In the beginning he refused to let his wife go and locked her in his mind(dream) and he remained apart of fantasy life, but as one can tell that all changed in the end.

well in my opinion the totem was jst about to lose it's momentum so if the camera would've stayed on longer then the totem would've stopped spinning....so i think that it was reality......

The "Dream team" has made the work, so Cobb back at home, but the director Nolan creeps the doubt's ambiguity, with the whirligig.

I think its reality because in Cobb's dreams he is wearing his wedding ring, and in reality he doesn't. So if you look closely, you can see he's NOT wearing it. Thus making it reality

Ok, the camera cut off in the middle, so we don't know. Why? Because they want us to either make up and ending and imagine the ending for ourselves, or there is going to be part 2. But the tip actually wobbled so it was most probably reality (at least that's how I see it)

i think it's in the reality cuz the spinning thing wobbles a bit and in a real dream it never wobbles.

They definitely created that cliff-hanger purposefully. I do not believe it was to foreshadow a sequel, but to create a lasting sense of suspense, if you will - never knowing whether Dom actually woke from limbo or not. Personally, I am, at this point, still undecided, as I see evidence that supports he woke up, as well as evidence that supports he remained in limbo. Although, unfortunately the evidence that suggests he remained in limbo outweighs the other, I believe. At first I thought he must have woken up, because he saw his childrens' faces. But that may not be true. He said to Ariadne that he wanted to call out to them, but couldn't. Well, at the end, he still didn't call out to them - it was the grandfather that said "Look who's here." Plus, they were the same age as they well the last time he saw them which, by the sounds of it, must have had to have been years ago. And in the beginning, when he talks to them on the hotel telephone, Philippa sounded at least thirteen, maybe fourteen. Well, the girl at the end of the movie was definitely not thirteen! More like seven or eight. I think that is the most convincing for me that he was still in limbo, because that is just outright, directly contradictory. Plus, when he spun his totem on the tabletop, it showed it begin to topple, but that does not mean he wasn't in limbo - earlier in the movie he said that Mal could make the top spin forever without toppling. Keyword: "make." Meaning she had to consciously cause it not to topple; therefore meaning the top could topple in limbo if she let it. And since Dom walked away from the top to go hug his children, it began to topple. So, actually, after writing all of this, I'm not undecided. I think he was definitely still in limbo.
Sorry if I rambled on forever; I like this movie a little too much. :P
