I had an interesting, but sadly non-lucid dream about elevators. In the dream, I was visiting a family friend in the hospital, except I never found his room. I got into an elevator to leave, but just before the doors closed, I saw him in the room directly across from the elevator. He was reaching out and I couldn't tell if he was waving good-bye or trying to stop me from leaving. The little detail that eluded me until I woke up was that this friend died two years ago.
