You guys know that there is a type of facial mask, it's like a white sheet with 3 holes for the eyes and mouth which suppose to hydrate and revitalize the skin? Well, there's been a few times when I walked thru the dark, dark cabin on international flights, suddenly I saw a ghostly face floating in the air looking like the mask in " Scary Movie ", it scared the daylight out of me for a second before I realized that was a lady wearing facial mask!
