Drop Ceiling Fan How Do I Know If My Ceiling Fan Is About To Drop Or Not?

How do I know if my ceiling fan is about to drop or not? - drop ceiling fan

In my room in my house, actually, I think ceiling fans are falling. Is there a way to know whether it really fall, or simply too staggering. I mean, I do not think the ceiling fan must vary greatly, especially when the leaves of the screws are tightened and the blades are balanced. Please give me a useful answer. My bed is under my ceiling fan, I would like to know if I can still use, or should I be someone for sure.
