What the hell? Can someone please tell my why this happened?

Sounds like the work of a shadow creature. Nothing to worry over, just know they like to stir things up to get negative reactions out of people. They basically feed off of negativity. Just try to stay positive and not to read into things too much, don't worry about what is out of your hands because you can't change anything. Shadow creatures are all around us, again don't worry about it too much. Like, ever misplace your car keys and you were sure you left them on the table but the aren't there? And you leave and come back 2 minutes later and BAM! there they are. That is the kinds of things they do, knock things off of sheves, hide stuff. Just little things like that. Hope I helped. you can google search it as well if you wish.
