Shutter Island

In “Shutter Island” (2010), inmate Bridget Kearns asks for a glass of water. When she “drinks” it, there is no cup in her hand. She also fake drinks with her right hand and sets a glass down with her left. This is probably because Teddy has a fear of water, and much like reality, his brain can’t handle it, because of what his wife did. So his brain literally blocks out the glass of water from her hand. It’s also why he’s incredibly seasick at the start of the film.
