I realized why this felt so creepy to me. It feels almost like Sarah's ghost exploring the surroundings after her death keeps placing her at the start of her nightmarish last day. Her father and uncle aren't there because theyre not dead like her and she keeps walking around like a time frozen purgatory.
lol, Naughty Dog made Joel's backyard even though you were not supposed to get back there. Also could you imagine if you could compete the game as Sarah walking around.lol.
This entire thing feels like the movie "Others" you know where the ghost don't know their dead and just wanders an empty deserted world where they are the only beings present.
