What the fuck happened? I came up with two scenarios of what I think could have happened and neither one of them is good. 

1. supernatural. Something supernatural happened. ghosts, demons, gremlins, idk. could be anything i guess

2. natural. the only natural explanation I could come up with is that since all of these doors lock from one side only (you cant have doors that wont open from the inside in public buildings, fire escape hazard). Someone could have been inside that closet, and decided to leave right as I was taking a piss. The reason I find this one so disturbing is that the person would have heard me jiggle the door, they would have known I just walked by 10 seconds before. but the only thing they couldn't have predicted was that I decided to use the mens room right as they decided to leave the closet. they... missed me. but that begs the question... what would have happened if I had kept walking down the hallway? 

I have no idea what happened here. But either way. It was not good.

Or maybe you jiggling the door could have caused a broom to move inside and open the door somehow?

Yeah ....because they lean all the brooms and buckets against the closed door
