I think the 'running without getting anywhere' symbolism is supposed to mean you feel out of control or helpless.

What about a dream where I'm at the office with a machine gun, and I'm walking around but just shooting people's coffee cups out of their hands?

Is that bad?

Yes, I think that's another thing that can trigger it. Sometimes I think the symbolism in dreams comes from the body and the mind picks an image that represents what the body is feeling, and sometimes I think it works in reverse where the mind is in a certain mood and it expresses it through an image associated with a certain bodily feeling, like in this case losing physical control. Pretty interesting to me to try to figure out how all that works! :)
