I've been told that being naked in a public place in your dreams can be interpreted as all of your insecurities are being exposed for all to see. I've had many of these.
I still have dreams where I'm back in high school, although not as many as I used to have. It's like "Oh, my God, I'm back in school, I'm forty-four fucking years old, and I'm still in high school!", and in the dream, I'm hoping no one notices that I'm old enough to be the father of all these students.
My most fascinating dreams involve water. It's like I'm navigating my way through an unfamiliar environment, a city that I don't recognize, and it's surrounded by water, flood waters, perhaps (epiphany: New Orleans just popped in my mind), and I'm trying to avoid contact with the water, for fear of drowning, disappearing, whatever. There's a famous Edward Hopper painting of a very spare hotel room, and the door's open, and all you see through the door is ocean. Just like one of my dreams.
I've dreamed that a friend of mine, a wonderful, much missed friend who died when he was eighteen, called me in the middle of the night to chat with me...
I've had other dreams where the love of my life came to see me, from wherever she is nowadays. My favorite dream of all time happened shortly after I got my discharge from the Navy, and I was living a miserable, depressed existence in my parents' house. In this dream, there was a knock on my door. I answered it, and there were three or four of my shipmates standing there, with big smiles on their faces, and they were beckoning me to come out on my front lawn. I did, and I saw another hundred of my shipmates standing there, wearing party gear, and coming over, and embracing me.
Some dreams are good, some not so good. All are fascinating.
