Hahaha this is definetly a case of 'remote on the bed' most people will have a certain place the bed they keep their remote and sure enough once a day minimum it will fall of the bed causing an apocalypse like crashing noise, does the object sound like it could be a remote?
Maybe it's a bag of some sort? Or shoes? When I lived in an apartment building, it sounded like the upstairs neighbors were fucking BOWLING. There was always at least once a night this loud clunk and roll from up there.
