I think more games should have ghosts and supernatural shit in their worlds but not tell the player about it or draw attention to it at all. That's pretty fun.
My Summer car has like at least 2 confirmed ghosts you can see and one can only be seen through a camera photograph like this is some Fatal Frame or Metal Gear Solid ghost photography shit, and My Summer Car is a game set in 90s Finland about building a car and being forced to marry because you impregnated a girl while drunk.
