The only thing that might get hurt is the lamp if it "walks" off the sub due to all the thunder!

Seriously, the problem may come more from possible transmission of vibration to the lamp or simply by being too close to the moving air it might distract all with rattle. Experiment when she is NOT around with a really deep bass track to see if anything in the room shakes, and adjust things accordingly. (With guidance from the "Decorator in Chief", of course!)
