I have a theory: Albert is remembering the past. the "disappearing face" isn't an actual curse or an "illness," it is simply what happens when one starts to forget the past. Albert doesn't "look" like his father — he IS the father. or rather, there's no "father" at all, it's just Albert, there's only one of him. and he has a fuc*** up memory. and all these "illusions" and "imaginations" he keeps having are just bits of his memory resurfacing, like something trying to fight its way to the surface of a frozen lake. maybe Asha wiped both their memories for whatever reason, or maybe that is the actual curse of the mansion — people forget, hence the "distorted" faces.
