I had dream the other night where I was staying in some kind of penthouse or something with a bunch of other people, and there was another group of people in a different identical penthouse. The penthouse didn't have a normal bathroom; it had a big locker-room type bathroom with one of those big communal showers, and for some reason everyone living there had to shower at the same time, but it didn't bother me because we all showered fully dressed. While I was showering, one of the other people got out of the shower early and called me to come look at something. She and a few other people were gathered around a set of those coin-op binoculars that they have at tourist sites, and she handed me a quarter and told me to put it into the slot and look through the binoculars, and I would be able to see into the other penthouse. When I did, I saw one of my childhood friends in the other penthouse, and he just said "Oh, gosh!" and then I woke up.
