I definitely have some bt devices around the house, but I'm pretty sure they're accounted for in the list of previous connected devices and if it wasn't something I have connected before it seems odd it would be trying to connect out of the blue, and my fiance was sleeping so I know no one in the house was using anything like that. There are some sketchy business on the other side of our back fence, but it's probably JUST close enough for a Bluetooth device to connect to my PC and when I went outside the front shortly after there was no one around (again, 5AM so most people are sleeping). The whole thing was just weird because I haven't had something like this happen in the years of having my PC constantly on in this house and every time I clicked deny access it popped back up, possibly because it was just sending a connect signal and not listening for a denial, but that's merely guessing because I don't have much knowledge on this.
