there's also a ghostly face in the opening credits in the lower right corner... but, i'm sure that's just my brain interpreting the shadows and shadings as such and really means nothing in the grand scheme of the game... as i'm sure all those other Ghost Immages people see in the Compilation of FF VII are of the same nature, the human brain peicing together light and shadow elements to form a cohesive image the brain can accept and recognize, wether it be there intentionaly or not...
i remember as a child i would look at the woodgrain panneling in our home and see all kinds of images in the patterns but i know and knew at the time that those images were there mearly as a coincidence... to this day i still see images and paterns in things most people don't notice, but i just accept that it's the artists eye to see what is really not there and form images where there truly is none... conspiracy buffs also share this trait...
