I woke up to a very loud noise, and got up from my bed to see white dust coming through beneath the door. When I opened the door, that's what I saw. A cleaner that was working that day had just passed through to clean the bathroom, she was barely through, so it could've ended bad for her. No one was hurt. The ceiling fell without any stimulation, and is from what we understand due to bad design and slacking from whoever installed it.
