during the last school year, i was working on an all nighter for an essay. from what i remember, it was roughly 2 am and i was the only person still awake at that point. i have a loft bed which is basically a bunk bed but with the desk on the bottom..i have a couple of lacy ribbons as decoration hanging around the perimeter of the bottom of the bed if that makes sense, and while i was typing one of the ribbons in front of me started swinging back and forth out of nowhere. i wasnt moving at all other than my hands for typing, no windows were open or anything so im still really confused as to what caused the ribbons to move on their own
