That's scary. I don't believe in ghosts but still scary. Σ(っ°Д °;)っ
In my old house, our doors are hollow so they are very light, any change in pressure in the house(wind from another room, another door opening or closing somewhere in the house or even switching the air conditioner on would cause a change in pressure and would close the open doors (vice versa for doors that are not fully closed) in my house. Maybe the air vent? It doesnt have to be the bathroom window, maybe another window was open or pressure changes from the hollow ceiling (=・ω・=)
Doors would slam shut pretty often in my house. Even when nobody's around... most often in the afternoon though.(since theyd all be closed by night(￣∇￣") )

So I was home alone last night . My mom and my siblings went out to do their work and I swear , this never happens . We have two bathrooms in our apartment . I was watching the TV after doing my schoolwork . One of bathroom doors was open . I was really concentrated on watching the TV and then a sudden THUNG broke my attention . it was bathroom door closing . Yes, logical explanation would be that it was the wind but I'm gonna be honest there is no small window or anything in that bathroom that could cause it . Didn't really feel scared since things like this happened at least once or twice but this one felt a little too strange (￣∇￣")
