Creepy detail in "Shutter Island"

In Shutter Island (2010) a woman being interviewed is given a glass of water, when she goes to drink out of it the glass disappears, then reappears when it is empty. "Teddy" is afraid of water after the incident with his wife and his reality is skewed because of it. pic.twitter.com/itPcz7Q0Yk
