I Suppose My Dream Self is on a Cruise

Various things occurred in this dream. First, I am on a boat on a cruise with John. We are walking down a raised deck inside the boat and we pass my parents. I am immediately nervous at everyone having seen us together. Next I am outside and there are three pools. The water is impossibly, beautifully, dark blue. My mother is there. We exchange a few words about John but I can't remember what they are. My general impression is that she is being nice but doesn't like him.
Later, John and I are outside on one of the decks. I never actually see the ocean but nevertheless believe I am on a cruise ship. Valerie is there. We start talking with her, although she is behind a pane of glass. She continually refers to her relationship with me as "when we were roommates." I shoot John a meaningful glance from the corner of my eye
