The interesting thing is that the camera felt very heavy.. I can remember definitely it having weight, which is odd since you don't usually feel much of anything in dreams.
One thing I've been sort of trying to do lately is relax my muscles. I find that my shoulder muscles are always somewhat tight. I do the occasional stretch, but I never seem to be able to loosen them up. Coincidence that I would feel them in my dream then? Hard to say, since the thing felt like weight, rather than a muscle that was tight. But since dreams are made of various real world elements all mixed together, it's within the realm of possibility that the two items are related.
Of course, if my subconcious is telling me that I've put some sort of "weight on my shoulders", it would be rather nice to be able to take the weight off, whatever that might be.
