What does the spinning top ending really mean in Inception?

[Jeffrey.R]

I just finished watching the movie and I’m still stuck on the final shot of the spinning top. My friends say it’s obviously a dream because it wobbles, but I rewatched it and to me it looks perfectly steady right before it cuts to black. Does that wobble actually happen, or are we meant to see it as a moment of pure ambiguity?

I watched it twice. The first time I swear there was a tiny wobble as it slowed toward the cut, the second time it looked almost perfectly steady right before the cut.

I think the wobble isn't a physics thing at all but a cue to doubt what we just saw; the film loves those tiny, almost imperceptible details.

Maybe the real problem isn't the top at all; maybe we're supposed to question whether the problem even matters?

I didn’t notice any wobble in my viewing; maybe it depends on screen size, lighting, or where you sit.
