Without Explanation

I had a dream a couple of nights ago that I was working in a very nice office, with all this beautiful wood paneling.  I was sitting at my desk, with a laptop open, playing a podcast, and I was looking through the drawers.  Inside were various medical tools, scalpels and the like.  I must work in a medical supply company? 
I think it's very strange to be dreaming about work.  And maybe a sign that I'm overworked, because don't normal people dream about sex or flying or being famous or something mundanely selfish?  I always dream about small moments without explanation.
