Yes, I'd say the party likely had a lot to do with it. Snakes are so tuned into vibrations, it's amazing. One of my rat snakes was uncharacteristically hiding the other day (she's normally out on her driftwood when not in shed) after I'd had to restrain her to medicate a very minor mouth 'ding', which she vigorously fought. I knew she was upset with me, staying in her hide, but when I removed the top of her tank the next night (for feeding time) out came her little face, eagerly expecting my "room service"- so much for her pouting. But my point is, she was very tuned in to just those little vibrations. So a lot of activity probably has your snake thinking "is the sky falling?" This should pass in a few days, hopefully- but do take your time with her anyway- she's just more sensitive & shy.
