You have to understand, they’re not ordinary doors.
There are many doors and drawers and other hinged pieces of wood over holes in walls, like empty eyelids, that exist every day. They stand where they should be, in walls, silent and concealing. Anyone can open them. Anything could be behind them, so that the simple act of walking through could change your life, but walking through one will not dissolve you and reform you anew.( When I speak of doors they are not metaphorical. )
