Nope, no fall was involved. I think what happened was not a factor of hitting the faucet hard enough, it was a case of hitting my head in the right (or I should say wrong) place. Last year I lived in a dorm where the shower knob was about sternum height. I was taking a shower and accidentally dropped the shampoo bottle, so I bent down to pick it up. As I was standing back up, though, I hit the direct back of my head on the knob pretty hard. I did not pass out, but I definitely saw stars. That's what did me in.
